Mechanical Behaviour of Natural Reinforced Polymer Composites with Hybrid Additives K. Kalaiarasan*, K. Venkatesh, R. Mukesh, K. Patterson, R. Badrinath Department of Mechanical Engineering, Christ College of Engineering and Technology, Puducherry, India

Abstract The implementation of natural fibres is the fast approaching ‘green’ economy based materials that are used in polymer matrix composites that are intended to replace the conventional synthetic polymer composites. Being plenteous fundamentally, natural fibres have been existed the primary form of natural resources for centuries. Considering that mechanical properties of composites are strongly influenced by the quality of the fibre/matrix interface and with eco-friendly properties like excellent energy absorption, low cost, biodegradability, non-toxicity and light weight, natural fibres have steered the attention of scientists and researchers towards them to find their application by replacing the synthetic fibres and plastic composites. Utilizing the combination of hemp and sisal fibres by using hand layup methods, the matrix composite are prepared. Following with the proper pretreatment processes have proved to featuring good mechanical properties of significant parameters which can be ultimately equipped in desired applications according to our needs.

Keywords: biodegradable, epoxy resin, hemp, hybrid additives, natural fibres

INTRODUCTION The usage of natural fibre reinforced composites in automobiles due to the low weight to strength ratio has turned the attention of researchers towards itself.

Particularly finding its application in automobile interiors natural fibre composites have a long history of being used as an alternative to fibreglass, injection moulded plastics and other less sustainable technologies. As epoxy resin is one of the excellent thermosetting polymer resins, it is used as a structural matrix material which is then reinforced by natural fibre materials. Also, epoxy base matrix composite has enormous potential to substitute the traditional metallic materials. Particularly, the FRC (Fibre Reinforced Composites) are used in load bearing, light-weight structures due to their superior mechanical properties compared to metals. Also, it is observed

from literature that there is a significant improvement on mechanical properties with epoxy matrix modification. Pervaiz and Sain[1] have investigated the energy consumption of glass and natural fibres.[2] Fibre reinforced (FRP) composites possesses interesting properties like high specific strength and stiffness, good fatigue performance and damage tolerance, low thermal expansion, nonmagnetic properties. Karmaker et al.[3] have shown that the biodegradability of natural fibres can contribute to a healthy ecosystem while their low costs and high performances are very interesting for industry. Sisal/jute fibre composites are environment friendly and user-friendly materials[4] and have very good elastic properties.[5] Li et al.[6] studied that sisal fibre is the promising reinforcement

Synthesis and Characterization of Poly(etherdiphenylene terephthalamide)-Metal Complexes in Heterogeneous Medium Sandeep Rai Shroff S R Rotary Institute of Chemical Technology, Bharuch, Gujarat, India GRP Limited, GIDC Estate, Panoli, Bharuch, Gujarat, India

Abstract Condensation of terephthalic acid and 4,4ʹ-diaminodiphenyl ether resulted in aminoterminated oligomeric poly(etherdiphenylene terephthalamide) (PODTA) using phosphorylation technique. Schiff base complexes of this polyamide were synthesized with salicylaldehyde and 2-hydroxy-1-naphthaldehyde complexes of Co(II),Ni(II) and Cu(II). All the synthesized polyamide as well as Schiff’s base complexes were characterized by elemental analysis, IR spectroscopy and magnetic susceptibility measurements. Thermal stabilities of ligand and its various complexes were compared by thermogravimetric analysis.

While, Co(II) and Ni(II) of the polymer metal complexes shown slightly inferior thermal stability than the PODTA, Cu(II) complexes exhibited superior thermal stability.

INTRODUCTION Polyamide–metal complexes are formed by the introduction of metal ions into polymer chain through pendant or terminal functional group.

The potential applications of coordination polymers are as high temperature lubricants, surface coatings, adhesives and constructional material as required in high speed aircraft and space vehicle.

Aromatic polyamides (aramids or polyaramids) are considered to be highperformance organic materials due to their outstanding thermal and mechanical resistance. Schiff bases have been reported in for their biological properties, such as, antibacterial, antifungal activities.[1–5] Their metal complexes have been widely studied because they have anticancer and herbicidal applications.[6–8] They serve as models for biologically important species.

Although many studies on polyamide– metal complexes have been reported, very little work seems to have been carried out on the introduction of metal ions into aromatic polyamide ligands through Schiff

base structure. Here we report the synthesis and characterization of aramidSchiff base coordination polymers using amino group terminated PODTA oligomer as ligand.

The aim of present work is to improve upon the thermal stability of the ligand by the coordination and develop a technique for surface modification of amino group containing polyamides in heterogeneous medium. In heterogeneous medium, the amino groups present on the surface of the aramid particles only will form the Schiff base complexes.

Therefore, free amino groups present on the surface of aramid film, sheet or fibre may be complexed to enhance the thermal stability of the material and to incorporate additional properties due to metal complexation.

Innovative Value Chain Development of Modified Starch for a Sustainable Environment: A Review A. Ashok*, C.R. Rejeesh Department of Mechanical Engineering, Federal Institute of Science and Technology, Kerala, India

Abstract Granular structure of starch is widely utilized in a variety of applications due to its universal abundance, relatively low cost, and ability to impart a broad range of functional properties to their products. However, most starches in their native form have limitations that make them less than ideal for the diversity of desired applications. For this reason, most of the starch utilized as a food or industrial ingredient is first modified, without changing the granular structure, to alter and improve the physical properties of starch polymers in accordance with the intended end use. Starch based materials present a great potential to play a major role towards achieving sustainable development. Starch is a natural glucosebased polymer that is generally considered as a potential candidate for developing biodegradable products. Starch is a versatile and useful polymer not just because it has low cost or obtained from natural resources, but also because of its physicochemical properties that can be altered through chemical or enzymatic modification. Starch modification accentuates their positive characteristics, diminish their undesirable qualities, or add new attributes. Different approaches have been used to overcome these limitations and increase the number of sectors in which starch-based materials can be used. This paper summarises the different pathways required to modify starch and its applications.

Keywords: blending, modification of starch, starch, sustainability, value addition of starch

INTRODUCTION Starch is the principal carbohydrates energy reserve in plants and is one of the most abundant resources in the biosphere.

Storage starch, which is abundant in the storage organs of starch crops such as corn, potato, wheat, cassava, etc., is also a principle source for human consumption.

Starch derived bio plastics being a renewable and biodegradable polymer with well-defined chemical properties offers vast potential as a versatile source for various applications. A vast range of native starches are available locally and its usage ranges from food industry to medical field.[1] Several value addition methods and new strategies are required to

meet the steady increasing demand for environment friendly ways of starch production, at lower costs.

By directing several metabolic reactions in close connection to starch bio synthesis or altering the flow of carbohydrate in the plant, the yield and structure of starch can be engineered. The main structural elements that can be readily analysed are the amylose concentration, the amylopectin and amylose chain length distribution, the amylopectin and amylose molecular mass, phosphate substitution and starch granule size distribution. All these molecular alterations have profound effects on the physical properties of the
