Description

This paper discusses the development of carbon fiber reinforced plastic (CFRP) technology for the field of lightweight vehicles, an endeavor aimed at tackling current global environmental issues. In the development of the Lexus LFA, in which TOYOTA adopted a CFRP body, we not only improved rigidity but also achieved weight savings using the integral molding process and a more flexible design. We have now begun studying CFRP using thermoplastic resin to apply it to CFRP technologies in the mass production of vehicles. For the future production scale, we will need to develop recycling technologies for CFRP in addition to the CFRP technology itself. The key to recycling technologies will be finding out how to separate carbon fibers from CFRP keeping the costs and energy consumption at a minimum. A variety of methods have been studied up to now, including, for example burning or melting methods. We feel an effective collaborative effort is now required so that we can approach many other related issues, such as disassembling of CFRP from vehicles as well as supply chain management strategies.
