Full CFRTP car bodies get boost


In 2011, Teijin (Osaka, Japan) built a four-seater concept car with a carbon fiber reinforced thermoplastic (CFRTP) body structure. The body was formed in one minute and weighs only 47 kg, merely a fifth of a comparable steel structure, achievements that represent a new world of mass production applications for carbon fiber composites..

Carbon fiber has 10 times the strength but just a fourth of the weight of steel according to Teijin Composite materials made of carbon fibers and resins are already widely used to reduce the weight of aircraft and other industrial materials. However, conventional thermoset-formed carbon fiber composites are rarely seen in mass production due to its slow tack time.
