Composites industry worldwide will see good growth over next 5 years According to Lucintel, a leading global management consulting and market research firm, the global composites market is anticipated to witness good growth with a compound annual growth rate (CAGR) of 3.5% over the next five years. Major drivers of growth for this market are double-digit growth in wind energy and strong growth in the aerospace market. Increasing urban population and high growth in the building and infrastructure development are other major drivers. Lucintel’s full report can be downloaded at www.reportbuyer.com/ product/3871133/ SA industry growing And the good news is that South Africa’s composites industry is alive, well and growing rapidly. We have an excellent composites manufacturing ability, one which we need to promote throughout the rest of Africa, and ultimately, globally. One of our industry’s most vehement protagonists, Oliver Dawson, who heads up the Composites Training Academy, believes that local composites companies need to take advantage of the opportunities offered to promote their capabilities. “Composites are still one of the fastest growing manufacturing sectors globally. The Composites Training Academy is mobilising behind some fantastic initiatives spearheaded by the Department of Science and Technology and the Department of Trade and Industry, in close cooperation with the private sector. If we continue in this vein, the future looks good – difficult, but good! We can’t sit by, and watch the rest of the BRICS countries take advantage of the opportunities this sector offers and be left behind, it would be madness!” he adds. Meanwhile, the Mandela Bay Composites Cluster (MBCC) is also doing great things to promote the industry. According to CEO, Andy Radford: “Composites can provide new avenues for industrial and economic competitive advantage and we are showcasing this by creating a composites corridor in Port Elizabeth, where composite applications will replace metal and cement where appropriate.” The MBCC has also mapped the value chain for the production and application of Basalt in composites and is at an advanced stage of securing local and global beneficiators and buyers for the mineral for use in composite materials.

COMPOSITES TESTING DIRECTORY, FIRST TIME IN SA Mandela Bay Composites Cluster (MBCC) have mapped SA’s testing capability for composites and compiled a handy table. By using the table you can quickly see which of the country’s 23 testing entities can test what, and whether the test has SANAS or ISO accreditation. The matrix, showing details for up to 300 specific tests, includes mechanical, chemical, physical, NDT and optical test methods.

number of innovative technologies enables researchers to explore processes that can then be scaled-up and commercialised to speed production times, reduce manufacturing costs and provide stronger, more energy efficient blades. A number of innovations are integrated into the design of the blade including impact resistant components, continuous fibre reinforced thermoplastic parts, and exterior shell components produced with less than half the emissions associated with wind blade manufacturing. www.iacmi.org

NASCAR TEAM TO HAVE FLANGE-FIT COMPOSITE OPTION

MBCC TEAM GROWS Two new faces at the Mandela Bay Composites Cluster are Sabelo Sibanda and Thulisile Volwana. Sabelo and Thulisile extend the reach of the Cluster and will be interacting with industry and particularly official cluster participants to assist in facilitating company benefits. “I believe the Cluster's new staff have the skills set and approach to assist a fragmented composites industry, comprising highly advanced and emerging start-ups make gains through product development, market access and supplier development initiatives that are part of the Cluster's services,” said Cluster CEO, Andy Radford.

IACMI DEVELOPS PROTOTYPE 9M WIND BLADE The Institute for Advanced Composites Manufacturing Innovation (IACMI) has developed an advanced technology prototype wind blade. The team investigated new technologies in a novel 9-metre prototype blade, exploring new materials and processes that could be used in manufacturing. Full-scale wind turbine blades average between 35 and 45 metres. Using the smaller prototype blade to test and validate a

NASCAR XFINITY Series teams will have the option of using a flange-fit composite body at three races later this season as the series moves toward incorporating the body into competition full-time by 2019. Approximately 90% of those expected to compete in the Richmond XFINITY Series race indicated they would compete with the new composite body. Unlike steel bodies which are welded to the chassis, composite bodies are bolted via bracing onto the chassis and can be removed and replaced much easier. The laminate blend material can be broken, but for the most part it retains its shape when struck.

FIRST 3D-PRINTED SUBMERSIBLE HULL Oak Ridge National Laboratory (ORNL) and the US Navy’s Disruptive Technology Lab, have created what they say is the military’s first 3D-printed submersible hull out of carbon fibre composite. The Optionally Manned Technology Demonstrator is a prototype vessel that could be used to deploy logistics capabilities and sensors. The company used big area additive manufacturing (BAAM) to make the six carbon fibre composites pieces of the hull in around four weeks, according to the researchers. While the cost of a traditional hull ranges from US$600,000 to US$800,000 and typically takes 3-5 months to manufacture, using BAAM reportedly reduced hull production costs by 90% and shortened production time to a matter of days.

PORSCHE ROLLING OUT CARBON FIBRE WHEELS Porsche is bringing an all-carbon-fibrereinforced plastic wheel to the market, saying it will be the first global automaker to offer the CFRP wheel when it debuts in early 2018 as an option on the 911 Turbo S Exclusive series. At 8.8kg, the composite wheel is 20% lighter than an equivalent aluminium alloy wheel, but Porsche says the wheels are also 20% stronger. That strength combined with lighter weight will improve performance with “more spontaneity in both acceleration and braking,” Porsche said. The wheels will be priced at more than 15,000 euros for a complete set.

Accelerated growth in composites in SA PRODUCTION AND APPLICATION OF BASALT IN COMPOSITES BEING PURSUED THE development and application of composites in manufacturing in South Africa is accelerating up a steep growth curve, according to the country's national composites collective, the Mandela Bay Composites Cluster (MBCC).

Basalt fibre reinforced LFT composites

Created with support from South Africa's Department of Trade and Industry, the Cluster has implemented projects to boost the productivity of local manufacturers and establish value chains to commercialise South Africa's emerging composites resources. Mandela Bay Composites Cluster MD, Andy Radford, said the Cluster had mapped the value chain for the production and application of Basalt in composites and was at an advanced stage of securing local and global beneficiators and buyers for the mineral for use in composite materials.

JUST BRIEFLY SOFTWARE CAN SPEED UP COMPOSITE ANALYSIS METROLOGY company Hexagon Manufacturing Intelligence has launched a composite inspection system which it says can inspect and analyse lightweight carbon-fibre components more quickly. The system includes HP-C-V3D Apodius Vision Sensor camera-based scanning hardware

designed to fit to a ROMER Absolute Arm with Integrated Scanner and the Apodius Explorer 3D software package. The system can carry out fibre orientation, geometry measurement and three-dimensional model creation and analysis, the company says. Until now, three-dimensional digitisation has required the sensor to be robot-mounted. www.hexagonmi.com

“The country and particularly the rural areas of the Eastern Cape, has vast dolerite reserves, from which global-standard Basalt can be viably extracted,” Radford said. “Basalt fibre mined from dolerite in the poorest regions of the Eastern Cape could be an economic game changer for the region. Processed at Mthatha, Butterworth, East London or Coega, basalt product such as reinforced bar can be shipped to Europe through France”, Radford said. The Cluster is doing the same with a crop grown largely in Kwazulu-Natal called Kenaf,

BASALT FIBRES Derived from volcanic rock, the beneficial characteristics of basalt fibre include excellent corrosion resistance, high abrasion resistance, and inherent fire resistance. Basalt fibre is known for retaining its performance at cold temperatures and for not being degraded by UV or electromagnetic radiation. It has uses in marine environments, concrete contact, and underground applications because of its high corrosion resistance.

rather than using energy, resinbased thermoset manufacturing is exothermic – it gives off heat,” Radford added. www.mandelabaycompositescluster.co.za

COMPOSITES CLUSTER TO ORGANISE WORLD-CLASS SHOW FOR 2018 HEARTENING news for the South African composites industry is that the Mandela Bay Composites Cluster (MBCC), with support from government and industry, plan to host a worldclass composites and advanced manufacturing exhibition and conference during the second half of 2018. Andy Radford, Managing Director of the MBCC says the

event is aimed at providing role-players with market access opportunities, both national and international. The trade event will be designed around the needs of buyers and suppliers in the advanced manufacturing sector, including composites, 3d printing, CNC, lasers and robotics.

AERONTEC AND MARICELL STRIKE DEAL ON PVC STRUCTURAL FOAM AERONTEC has been appointed the official distributor for Maricell PVC foams in Southern Africa. Maricell has been manufacturing rigid PVC foam since the 1970s and has an annual production capacity of over 100,000 cubic metres. Maricell supplies the Mycell and Lycell PVC brands of expanded rigid foam with 100% closed cells, both of which have

marine approvals. Mycell is the standard PVC product, while Lycell is manufactured from the upcycled Mycell trimmings which are bonded and heat-cured to produce a laminated foam that boasts improved structural properties. Both Mycell and Lycell can be thermoformed at 100-120°C, at which temperature the foam can be moulded to any curvature. This obviates the requirement for sawing kerfs in the foam to make it contourable. The kerfs increase lead time for supply of

the foam, increase the mass of the core and reduce the shear properties. Aerontec has invested heavily in automated equipment to cut and drill the PVC foam products at their warehouse in Cape Town. This significantly reduces the lead time to supply the customers their required foam thickness and finish.

Point Break Composites hosts MVP flex moulding expert

A MORE EFFICIENT WAY OF CLOSED MOULDING CAPE Town based Point Break Composites (PBC) welcomed a group of around 40 local composite industry members to a one-day workshop presented by MVP’s resin infusion specialist, Charles Tur from France, earlier this year to showcase the latest in flex moulding systems from MVP (Magnus Venus Products). The workshop gave attendees an insight into how this transfer of technology would allow them to easily incorporate the flex moulding process into their production. Matthew Willett, MD of Point Break said that MVP closed moulding systems focus on customers in the composite industry who are looking to go from open moulding parts to a more efficient way of closed moulding.

“When the switch happens, there are many benefits for the customer with reduced emissions, higher quality parts, cleaner facilities, and more efficient work environments,” he explained. Many customers have been able to successfully move production from open moulding or light RTM, to the flex moulding process in a very short period. “PBC has been an authorised MVP distributor for around three years now. I have been for training in the USA and continue to stay close to MVP developments. We sell and service their equipment and carry most spares needed for the equipment my customers use,” said Willett. PBC will also offer training and work closely with customers for MVP resin infusion equipment

and processes. Willett said that the flex moulding process offers the following advantages: • a mix/meter infusion system provides a direct feed to the infusion membrane, eliminating the need to pre-mix resin and the use of consumable tubing and fittings • increased precision through the use of new accessories, including the pneumatic pressure vacuum sensor (PPVS-Infusion) • a new ‘lockable’ reusable membrane in addition to traditional vacuum bag infusion • MVP’s patented seals lead to large resin channels that collapse and disperse the resin in the

channel, reducing costs with resin wastage, and leave little visible evidence of the resin channels. • universal membrane fittings provide a secure and quick connection for the connection valves. • MVP supply universal fittings that can be used for plastic bag infusion, silicone membrane infusion and light RTM. “The silicone membrane gives a little more leeway than LRTM, and it is much faster than the plastic film. The biggest value is actually the Resin Infusion Machine, which can be used with plastic, silicone or LRTM. MVP boasting rights are the metering and mixing systems that they have, and this is essential for this process. Why leave it to chance of mixing catalyst by hand, and leaving it in a bucket?” said Willett. “Using the MVP Patriot Innovator with all the MVP accessories as a system to infuse your part gives you the means to reproduce a part, time after time, consistently

Why use the flex moulding process? Film infusion moulding, using either infusion films or reusable films made with silicon, polyurethane or latex membranes, has slowly gained popularity over traditional closed mould methods. The costs and learning curve involved in mould tooling are much lower with film infusion than the traditional rigid light RTM double mould set alternative. However, one of the challenges in the film infusion process has been a lack of emphasis on the improvements of feeding resin under the membrane. In the past, it has been normal to pre-mix the resin in a separate container and have the vacuum ‘draw’ the resin into the mould through a number of ports strategically placed in the infusion membrane. This method produces good results, particularly with large parts such as boat hulls and large wind turbine blades. However, there was still a need for a better solution to the continuous renewal of feed pipes, reservoir cleanout, waste of resin after infusion and the labour required for each moulding cycle in setting up the tubing and establishing the vacuum connection security. In answer to these challenges MVP developed a flex moulding process package that consists of injection systems, accessories and seals designed to optimise infusion. www.mvp.com www.pointbreakcomposites.co.za

Full size composite replica Spitfire fighter aircraft for Lesotho ALL (GRP) AIRCRAFT BODY PARTS USED MATERIALS FROM SCOTT BADER THE Spitfire Heritage Trust has recently completed a major project, successfully building from scratch an exact, full size ‘all fibreglass’ replica of the iconic WWII ‘Battle of Britain’ Supermarine Spitfire Mk VB (Type 359). Designed by Reginald Mitchell and produced from 1938-1948 at Supermarine Aviation where Mitchell was employed as an engineer, the original Spitfire fighter-interceptor was the first ‘all-metal’ stressed-skin aircraft. All of the glass reinforced plastic (GRP) aircraft body parts manufactured for this replica plane were moulded using laminating resins and structural adhesive materials supplied by the project’s principal sponsor Scott Bader, which donated the majority of the composite materials used to construct the Lesotho replica Spitfire. This authentic, GRP replica Spitfire has been specially built in the UK for the Kingdom of Lesotho

The bare FRP mouldings, manufactured in early 2015 using Crystic 489PA and Crystic® 2.414PA UPR hand layup laminating resins, supplied by the project’s principal sponsor Scott Bader

in southern Africa by a dedicated team of volunteers from The Spitfire Heritage Trust. The Lesotho replica Spitfire project came about to recognise and pay tribute to the generous ‘Gift of War’ given in June 1940 by the people of Basutoland, with a population of only 400 000 at the time. The response to the war funds appeal was overwhelming, raising sufficient money from donations to pay for the (then) costs of manufacturing 24 Spitfires, so providing much needed new fighter-aircraft for two full strength Royal Air Force (RAF) Spitfire fighter squadrons. From this ‘Gift of War’ donation, No. 72 (Basutoland) Squadron was born in 1940 and continues today as an active RAF training squadron, in which trainee pilots now fly the RAF’s advanced trainer the Tucano T1, built under licence by Shorts of Belfast, before going on to fast–jet training.

Replica production team The Lesotho replica Spitfire was manufactured in Victoria, close to St Austell, Cornwall in the south west of England, using factory space, facilities and GRP expertise provided by Paul Ching, MD of Evolution Boats Ltd. Paul Ching is a master mould designer and keen Spitfire enthusiast, who brought invaluable experience to the team having previously built a FRP replica Spitfire IIa for the RAF, which is still on permanent display at RAF High Wycombe (www.raf.mod.uk/ rafhighwycombe/). Being a volunteer-manned project, it took a little over four years for the small production team to complete the Lesotho Spitfire replica, which had to be completed and supplied this year to tie in with it being the 50th Anniversary of Lesotho’s Independence from Great Britain. Working alongside Ching, and the mainstay of the Spitfire Heritage Trust Lesotho

Work in progress – closing the wings and camouflage painting the fuselage and then the wings prior to applying the decals represented an enormous step forward for the project in 2016. The stressed wing skins, supported by rib and I-beam spar components, were all specified with Crystic 489PA UP backup resin due to its elevated temperature performance and were fully post cured. Crestabond M1-30 structural adhesive was used to join the upper and lower FRP wing sections together, as well as for the internal FRP spars in the tail and fuselage, as well as for bonding in metal inserts where needed

project production team, was replica manufacturing veteran Patrick J. Mitchell, who has worked on many similar projects, including previously building four other replica Spitfires; while not related to the famous Spitfire designer R.J Mitchell, with whom he shares the same surname, Pat (P.J. Mitchell) feels connected ‘in spirit’, given his passion for the aircraft. The team started from scratch, with the key first stage of the project being to fabricate the individual patterns and plugs. New moulds were produced for each of the GRP parts required to produce the replica propeller, and the monocoque composite sections which make up the fuselage, wings and tail sections; exact dimensions were achieved at this critical mould making stage by copying off an existing original aircraft. Once all the moulds had been produced and checked, the next stage of the project was to start laminating the FRP parts, section by section. FRP technical challenges For this static, display replica aircraft, using hand lay-up glass fibre - UPR resin based laminate systems were

technically sufficient for moulding the GRP parts. However, there were still a number of technical performance-in-use considerations to ensure the correct choice of laminate system for specific sections of the aircraft to ensure that key areas would have the necessary mechanical and physical properties needed to cope with being exposed long term to the elements.

Pedestrian bridge presents FRP DECKS RESULT IN CONSIDERABLE SAVINGS COMPARED WITH A STEEL STRUCTURE THE new lifting bridge over Rhyl Harbour in North Wales, serves as an additional crossing for pedestrians and cyclists. Spanning the River Clwyd from Rhyl’s West Parade to a newly created public area on the Kinmel Bay side of the river, the elegantly opening lightweight bridge named ‘Pont y Ddraig’ has become an iconic landmark attracting visitors. Hundreds watched the two lightweight composite decks – or

dragon wings – being lifted into place earlier this year. In response to a tender call from Denbighshire County Council, Ramboll and Dawnus developed a design proposal consisting of two mirroring, 30m-long decks, which are hinged on a central caisson and lifted by cables running up to a central mast. At almost 50m tall, the mast is stayed by a rigging similar to a sail boat and makes the bridge and the

harbour visible from miles around. The mast houses the pulley mechanism and lifting cables. To balance the lift, the decks, engineered by Gurit (UK) and built at AM Structures using many Gurit materials, are lifted simultaneously. The use of advanced moulded fibre reinforced plastic (FRP) for the bridge decks was an integral part of the design concept to save as much weight as possible to make lifting

Solution to an architectural challenge! EXTREMELY LOW-WEIGHT, HIGH STIFFNESS STRUCTURE WITH DECOLITE™ FRASCADA Projects, a specialist manufacturer of composite architectural cladding panels using unique and innovative processes, recently completed a massive ‘floating yacht’ light fitting for the new Table Bay Mall in Cape Town using a unique product range called Decolite™. Decolite™ was introduced in 2002 by the company and has evolved into an industry standard for high quality lightweight decorative finishing products. The original spec was to construct the light fitting/mo-

bile from steel and timber which would have weighed in at a mammoth 6 tons! However, this proved to be far too heavy for the support. Frascada Projects, together with AMT Composites, investigated how this structure could be dramatically reduced in weight, whilst maintaining the excellent architectural appeal. Derek Frasca from Decolite™ opted for a flame retardant EPS core and then laminated thin glass-fibre skins with a specialised FR resin system from AMT Composites. The result was an extremely low-weight,

interesting challenge cycles fast and energy efficient. It also would result in considerable savings compared with a steel structure and allowed a sculptured deck shape, which provides a striking, iconic sight when the bridge is opened. The design proved to be successful, and AM Structures was approached for the fabrication of the decks. Gurit was contracted by AM Structures to carry out the detailed engineering of the bridge decks, which presented some interesting challenges. The decks are very slender, partially for aesthetic reasons, but also to ensure that the inshore lifeboat would have sufficient headroom to

pass under the lowered bridge at all tide levels. Detailed consideration of the dynamic behaviour of the bridge under pedestrian loading was also required. The bridge was designed with predominantly glass reinforcements with longitudinal stiffness enhanced by local planks of carbon fibre. Gurit made extensive use of finite element analysis to carry out transient dynamic analysis of the bridge using load models from Eurocodes. A number of load conditions were analysed, corresponding to groups of pedestrians walking and running over the bridge, in addition to a crowd loading case. This analysis led to optimisation

AMS ballistic protection solution defends against pirate attack THE SOLUTION HAS RECEIVED STANAG LEVEL II CERTIFICATION FOR ARMOUR PIERCING PROTECTION THE true value or quality of something can only be judged when it's put to use - the results are what counts! Advanced Materials Solutions (AMS) in Stikland, Bellville in the Western Cape, recently received unambiguous evidence that their lightweight, composite ballistic protection solution for a series of wheelhouse structures installed on patrol vessels off Nigeria did just what they were supposed to – protect the crew from automatic gun fire! AMS was commissioned to develop and construct 10 composite ballistic protected wheelhouse structures for Nautic Africa who was supplying patrol vessels to the oil industry off West Africa. The project was completed and the wheelhouses delivered. In September one of the patrol vessels came under heavy attack from pirates. The patrol vessel suffered multiple hits, but nothing penetrated the

wheelhouse structure. Johan van Niekerk, MD of AMS said the clients were obviously very happy. “We were also very pleased to learn that our composite solution had been so effective,” he added. AMS will send a team to Nigeria to repair the wheelhouse. AMS is the only company in the Western Cape who have the intellectual property (IP) to manufacture components using their composite ballistic protection solution. The IP used was developed by Johan and his team at AMS over several months of trial and error, testing and more testing done at Armscor. Johan explained that the composite ballistic protection solution AMS developed includes several layers of different composites laminated together. Using a vacuum infusion process, the protected areas of the wheelhouse were manufactured using 16mm foam

Ballistic Ceramics in various forms and compositions, Al2O3 in different grades (white to cream), SiC (dark gray) and B4C (black)

on the outside with a 20mm layer inside, providing thermal and sound insulation. The ballistic protection layer – comprising specialised ceramics – is integrated into the inside layers. For the unprotected sections of the wheelhouse, AMS used 600g/m2 glass fibre with a PVC foam skin of 55kg/m3. “We’ve recently completed even more testing and have managed to reduce the area density from 48kg/ m2 to just 26kg/m2,” said Johan. “The same protection using steel would weigh about 70kg/m2 if 9mm Armox 500 – a Swedish ballistic armour steel – was used. The solution is certified to the STANAG Level II protection level. This means that the composite ballistic protection solution can protect against penetration by gunfire using ammunition up to 7.62x51mm NATO and includes 5.56x45mm SS109 and 7.62x39mm or AK-47 armour piercing

incendiary rounds. “Through trial and error, and a lot of testing, over a period of about six months we decided on using a specific ceramic that fractures and absorbs energy, as well as developed a specialised adhesive that can resist the very high temperatures that would be caused by incendiary ammunition.” It was a significant learning experience for the team at AMS, but one they eagerly took on and successfully achieved. www.advancedmaterials.co.za

Composites version of S\V14 may become reality A 4-METRE OCEAN SAILING BOAT FOR DISABLED SAILORS Part 1: Over the next couple of issues of Composites SA, we’ll take you through the fascinating process followed to build the S/V14. WHAT began as a philanthropic gesture to design a low-cost sailing keelboat specifically for disabled sailors, has morphed into a significant challenge and serious passion for Cape Town-based naval architects, Alex Simonis and Maarten Voogd of Simonis Voogd Design. It all started in October 2015 when Peter Jacops, a specialist inspector for the certification of yachts, posted on Facebook challenging naval architects to design a low-cost sailing boat specifically for disabled people and make it freely available to all. The result – with 200 to 300 hours of labour, approximately R115 000 for materials (including plywood, steel and a revolutionary seat tilting mechanism), disabled sailors around the world now have the opportunity to own a fullyfledged open sailing boat – the S/V14 – that caters for a wide range of disabilities in a oneman and two-man version. All the information needed to build the boat, including 120 detailed drawings are available free on the internet. The only requirement to download and start building is a pledge that the boat will be used by or with a disabled person.

The first prototype of the S/V14 was built by the Robertson & Caine shipyard in Cape Town, using 11 sheets of plywood and one sheet of steel. Ten further prototypes are going to be tested around the world, including Thailand, New Zealand, USA, Belgium and The Netherlands. The project has received support both far and wide from the industry, including companies like Aerontec, AusThai Marine, Blue Peter Marine, Northern Sails, Nautique TV, Southern Spars, Advanced Material Solutions and many more. A composites alternative – even more affordable This is a significant milestone in the sailing world; however, Alex explains that the mammoth task of reading through and understanding 120 drawings and other detailed instructions could put off the more feint-hearted. And because of this consideration, Alex and his partner are now in the process of investigating ingenious ways of manufacturing the hull and deck from composites, but still keeping

it affordable. In the early design stages of the plywood version of the S\V14, Alex investigated the feasibility of a GRP boat made in a female mould so that it could be produced quickly and cost-efficiently. However, it soon became obvious that this option could only be realised using professional boat builders who would have to add their costs, resulting in a boat that was not affordable. Another problem was that manufacturing the moulds needed would also be expensive and add to the overall costs.

Alex explains that the actual composite materials needed would cost just half of the plywood version and the labour hours needed to build the entire boat would also be significantly reduced. However, never one to back off from a challenge, Alex has used his passion and connections to encourage companies like KZNbased NCS Resins to manufacture the moulds needed for free, while the University of the Transkei has offered to do the CNC milling at no charge. Also, working together with Oliver Dawson at the Composites Training Academy in Cape Town, Alex hopes to be able to convince the Academy to use the laminating of the hull and deck as a training exercise. Trainees will be given the opportunity to work on a ‘real’ project – a 4-metre “miniature Volvo Ocean racing boat”, as Alex describes it. “I am very impressed with the industry’s response here and abroad,” says Alex. The detailed drawings and instructions to manufacture the composite version of the boat will also include various moulding

options – hand lamination, vacuum infusion and resin transfer moulding. “It would be wonderful if individuals could be trained using these different methods, using our boat to work on – a true synergy of outcomes,” says Alex. “Essentially, the aim is to use the building of the hulls and decks as a training experience, then have these transported to a central point where they will all be quality checked. From there we can sell the hull and decks as part of the home-build kit for much cheaper than the plywood version,” he explains. And Alex’s vision doesn’t end there! He would like the project to “go global” so that more disabled sailors around the world are given the chance to buy and build an affordable sailing boat. As more and more disabled sailors around the world start sailing, the sport will once again gain momentum and ultimately be re-instated as an Olympic sport. Sailing was introduced to the Paralympic Games as a demonstration sport in 1996 and became an official Paralympic

sport in the 2000 Summer Games. In late January 2015, the International Paralympic Committee dropped Paralympic Sailing from the 2020 Tokyo Paralympic Games as “it did not fulfil the IPC Handbook’s minimum criteria for worldwide reach.” “I’d like to see 3000 boats built over the next three years and back in the Olympics,” says Alex. “All the tooling work is ready – we just have to begin.” www.sv14.org

Continuous-fibre-reinforced backseat 40% lighter TEPEX dynalite continuous-fibre-reinforced, semi-finished thermoplastic composites are finding new applications in vehicle interiors. One example is the backseat system of an off-road vehicle made by a European automobile manufacturer. The centre backseat is equipped with a load-through that enables the backrest of each seat to be folded down individually. This load-through component is produced by shaping and back-injecting Tepex dynalite. The new component is more than 40% lighter than its steel counterpart. Multiaxial Tepex is a new development from Bond-Laminates, which makes the

composite sheets significantly stronger than before by combining the Tepex fabric with tapes in a technically complex process. The semi-finished product for the load-through has a core consisting of four layers, each 0.25mm thick, which have a fibre orientation of +45 and -45 degrees relative to the component’s longitudinal axis and are arranged symmetrically. They absorb the torsion forces. In contrast, the bending forces are absorbed by the two outer layers, each 0.5mm thick, in which 80% of the continuous fibres are in the direction of force. www.bond-laminates.com
