Teijin Limited announced 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 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.
Going forward, Teijin intends to develop mass production applications for CFRP in automobiles and many other items that require certain levels of structural strength, such as machine tools and industrial robots.
Using new intermediate materials, Teijin developed its new technologies for the press molding of CFRP within just one minute's time. The technology also is simpler than conventional methods. In addition, Teijin developed technologies for welding thermoplastic CFRP parts together, and also for bonding CFRP with materials such as steel.
