Recycled composites and flax-reinforced composites have been employed to manufacture components for the Lola-Drayson B12/69EV, an all-electric prototype racing car that seeks to improve the environmental image of the resource- and fossil fuel-hungry motor racing industry.
Jointly developed by Lola Group (Cambridgeshire, UK) and Drayson Racing Technologies, the 850-hp Lola-Drayson B12/69EV is destined to take part in the FIA Formula E World Championship Series for electric vehicles in 2013.
Lola’s use of recycled composite materials follows the completion of a collaborative research and development program involving Umeco (Warwickshire, UK), WMG at the University of Warwick, and ELG Carbon Fibre Ltd. (West Midlands, UK). Carbon fibers from out-of-life MTM49 epoxy prepreg were reclaimed by ELG and then re-impregnated with Umeco’s MTM49 toughened epoxy resin. WMG, Lola and Umeco performed a series of tests to determine the mechanical and impact properties of the material, with comparisons being drawn against the original virgin prepregs. Test showed minimal loss of strength and similar fiber stiffness to virgin prepreg. Lola has since manufactured parts for its Lola-Drayson B12/69EV using this product....
