Teijin: Mass Production Technology for CFRP

Teijin Limited, Tokyo, Japan, announced today that it has established the world’s first mass production technologies for carbon fiber reinforced plastic (CFRP), achieving a significant reduction of the cycle time required for molding automobile cabin frame to less than one minute. The breakthrough overcomes one of the biggest challenges in the industry and represents a long stride toward the use of carbon fiber for the mass production of automobiles and other products.

Teijin’s new technologies include intermediate materials made of thermoplastic resin instead of conventional thermosetting resin for molding-use CFRP. Teijin also developed technologies for welding thermoplastic CFRP parts together and for bonding CFRP with materials such as steel, both of which will help to reduce the use of metal in manufacturing processes.

To demonstrate its new cutting-edge technologies, Teijin has developed an electric-vehicle (EV) concept car that features a cabin frame made entirely from thermoplastic CFRP and weighing only 47 kilograms, or roughly one fifth the weight of a conventional automobile’s cabin frame.
