At the upcoming Advanced Engineering Show, Composites Evolution will be launching its new range of aligned Biotex Flax tapes, offering significantly improved performance compared to woven fabrics, at a lower cost.
Aligning the flax filaments in a tape means that there is no twist in the fibres (unlike most natural fibre yarns), giving the same stiffness for weight as glass fibre. In parallel, because the spinning and weaving steps are eliminated from the production process, the final product cost is lower than conventional woven fabrics.
Biotex Flax tapes can replace layers of carbon fibre in a laminate to create micro-sandwich structures with equal bending stiffness to all-carbon laminates, but with reduced cost, reduced weight, increased shock absorption and improved environmental impact.
The tapes have also been used to produce hybrid flax/carbon spread tow fabrics, which offer superior properties due to the high degree of fibre alignment and low crimp, alongside highly attractive aesthetics. These materials are particularly suited to sporting goods.
Biotex Flax tapes are suitable for resin infusion, resin transfer moulding and prepregging processes, using a wide range of thermoset resin systems. In addition, Composites Evolution also includes prepregged tapes as part of its Ecopreg PFA range of materials, giving a 100% bio-derived structural material.
Gareth Davies, Sales Manager at Composites Evolution said, “Whilst we will still carry a range of woven fabrics where aesthetics are critical to an application, these new unidirectional tapes offer a step change in performance for cost, especially when used as part of a multi-layer or hybrid layup. It’s rare that a company can offer improved performance and lower cost in one hit, and we’ve received very positive reactions from initial trials with customers.”

The latest version of VERICUT machine simulation, verification and optimisation software, V8.1, will be featured on CGTech’s stand at the MACH 2018 manufacturing trade show in Birmingham, UK, on 9-13 April.
Cevotec has announced that a SAMBA Series Patch Placement system is now available for processing thermoset prepreg material.
North Thin Ply Technology (NTPT) and Richard Mille have signed a long-term collaboration and exclusive supply agreement. The new multi-year contract will see NTPT develop and provide its lightweight thin ply materials exclusively to Richard Mille for horology, jewellery and luxury stationery items.
