Matrix material characteristics High strength-to-weight ratio DIAB’s continuous development of the Matrix series ensures you have outstanding properties at the lowest weight for your needs.

Excellent fatigue strength Matrix materials’ excellent performance over time in dynamic loadings provides durability and long life for applications.

Exceptional peel strength The Matrix series’ material composition, mechanical properties and cell structure enable excellent chemical and mechanical adhesion properties.

And sustainability, too An application’s environmental impact is related to two main criteria: its lifetime and weight. Matrix core materials’ outstanding performance over time, in combination with excellent strength-to-weight performance, not only provides durability and long life, but also decreases weight. The raw material also has a low carbon footprint, as well as lower energy consumption in manufacturing compared to other raw materials used in foam cores. These characteristics, along with available recyclable and reusable alternatives, make the Matrix series a good environmental selection.

Compatibility The Matrix series grades are compatible with all main resin types. High thermal stability Good heat resistance makes the Matrix series a valuable material selection also at elevated temperatures. Low resin uptake Due to small cell size and a closed cell structure, the Matrix series provides low resin absorption.

Making you more competitive

Good insulation properties The Matrix series’ composition provides excellent thermal and insulating properties. Easy to process Matrix materials are very easy to machine and process into any shape or form, and can be used without the need of special consideration or machinery.

Focused performance


The Divinycell Matrix series High-performance core materials The Divinycell Matrix series from DIAB enables you to focus the performance of your composite application in terms of weight, cost and quality. Based on the idea that you should be able to closely match the core material to your requirements – and thereby avoid over-engineering your applications – the Matrix series grades are positioned based on mechanical property to as low density as possible. This enables us to offer products relevant to industry requirements and in right relationship to each other – invaluable for designing applications for optimum weight, cost and quality. Now, with the addition of Divinycell Matrix 10-8, you can experience the benefits of our best product ever – and, together with our other products and services, probably the highest performing line of core materials available on the market.

Core

Matrix 7-7 meets the DNV requirements for decks in marine leisure craft at probably the lowest weight in the industry, as well as a wide range of wind blade specifications.

Optimized Performance Well integrated into the full DIAB offering, the Matrix series enables our customers’ to create more effective designs according to their specific needs and requirements. The series is strategically developed to optimize the top items on the agenda for sandwich application manufacturers – namely weight, cost and quality.

Matrix 10-8 provides excellent mechanical properties at low weight, and with improved temperature resistance, allowing tougher process conditions.

7,2 MPa

Different geometries require different cuts in order to keep resin consumption low, affecting weight and cost. In this example, finishing selection for this section is based on two needs: production efficiency and impregnation quality.

Divinycell Matrix 11-9 With its unique mechanical properties, Matrix 11-9 is an excellent complement to DIAB’s range of foams – enabling structurally optimized designs.

The Matrix series complements DIAB’s Divincyell H range perfectly. The wide range of mechanical properties enables designers to optimize their applications by selecting the most precise core materials for their needs – resulting in decreased weight and increased competitiveness.

Shear range

4,5 MPa

Your design objectives, manufacturing process, and the geometry of your application all play important roles in determining which finishing options to use. For example, as geometry often differs throughout an application, DIAB uses different finishing when making kits to optimize flow and fitness. With our wide range of finishing options in combination with our broad competence in core materials, composites design and manufacturing, we help ensure you get an optimal selection.

Performance without compromise

Mechanical requirements often differ throughout an application. The mechanical properties of the Matrix series grades are evenly distributed and complement each other. This enables designers to use a core that fits the requirement in a particular part of your application – maintaining the same safety factors and avoiding overengineering. Not only can you decrease weight while preserving strength, but you can also achieve significant cost savings.

With DIAB’s kit concept, each piece is pre-cut, shaped and formed as necessary and numbered to fit exactly into its designated place in the mold. The kit can consist of sheets only or 3-D shapes made with CNC machining. By eliminating the on-site shaping and cutting of flat sheets, you can substantially reduce build times and save labor and material cost. In addition, with the easy assembly and exact fit, you can achieve a consistently high quality in less time. Each kit is designed based on the customer’s drawing using materials with different mechanical properties based on loading requirements. Kits are delivered in precut, numbered parts – avoiding scrap and significantly improving the layup time. In addition to the savings you have in time, cost, and scrap, DIAB’s kits ensure perfect fit for each part to yield the highest-quality finished products.
