Composites Evolution is a supplier of innovative, sustainable composite materials, including reinforcements, resins and intermediates based on natural and recycled feedstocks.

Their principal product line is Biotex high-performance flax reinforcements and impregnated sheets which provide the high performance and easy processing normally associated with glass fibre composites but with reduced weight and environmental impact. Biotex uses a unique Twistless Technology to ensure a high degree of fibre alignment and is suitable for semi-structural and decorative applications in sectors such as automotive, construction, marine, sports and consumer goods.


Composites Evolution new development includes flax-epoxy prepregs, flax spread tow fabrics and coloured flax fabrics.


A new range of Biotex flax-epoxy prepregs have been developed to provide a low weight, sustainable option for producing high quality composite parts. The prepregs can be processed by vacuum bagging, autoclave or press moulding, resulting in components with good mechanical properties and natural aesthetics. The flax-based prepregs can be used on their own or in combination with glass or carbon-based prepregs to obtain hybrid laminates with an interesting mix of properties.

Also on display is a novel ultra-light, high performance spread tow fabric produced by Oxeon using Biotex Flax/PP tapes supplied by Composites Evolution. The new variant of TeXtreme® Spread Tow reinforcement from Oxeon has 40% higher modulus than the equivalent yarn-based fabric due to the highly aligned Biotex tapes and ultra-low crimp provided Oxeon’s unique Tape Weaving Technology.

For customers wanting to make self-coloured biocomposite mouldings, Composites Evolution have recently added coloured flax fabrics to their Biotex product line. A wide range of colours are possible and the fabrics can be used with standard composite resins and moulding processes.
