Aligned Flax Tapes for Maximum Performance and Minimum Cost
At the upcoming JEC World 2016, Composites Evolution will be demonstrating applications based on the 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, “These new Biotex unidirectional tapes offer a step change in performance for cost, especially when used as part of a multi-layer or hybrid layup. We’ve received very positive reactions from initial trials with customers in a number of sectors and we are looking forward to talking to prospective designers, laminators and component manufacturers about these next generation reinforcements about Biotex being introduced into their products.”
Composites Evolution will be exhibiting their new tapes, wovens, flax / carbon hybrids and biobased resin systems at the JEC Show, Stand M66 Hall 6.
