Composites Evolution (CE, Bridge Way, Chesterfield, UK) has developed a range of carbon fiber/flax hybrid reinforcements, offered as an alternative to carbon fibers. CE says the inclusion of flax improves vibration dampening performance, reduces part weight and reduces environmental impact compared to carbon fiber alone. CE suggests three fabric forms to maximize the hybrid's utility: woven yarns, spread tow fabrics and a layered hybrid approach. In the layered hybrid approach, one or more layers of carbon fiber are replaced with CE’s Biotex Flax to create multilayer, micro-sandwich structures with equal bending stiffness compared to carbon fiber laminates, but with reduced cost, reduced weight, increased shock absorption and improved environmental impact. One example in the Biotex range is a 180-gsm 2x2 twill hybrid fabric that is aimed at the automotive and sporting goods industries and would suit complex structural and decorative parts.
