GM and Teijin to co-develop carbon fiber composite technologies for potential high-volume use in GM vehicles

General Motors and Teijin Limited., a leader in the carbon fiber and composites industry, will co-develop advanced carbon fiber composite technologies for potential high-volume use globally in GM cars, trucks and crossovers.

The two companies signed a co-development pact that involves use of Teijin’s carbon fiber reinforced thermoplastic (CFRTP) technology (earlier post) , a faster and more efficient way to produce carbon fiber composites that potentially could be introduced on mainstream vehicles. For Teijin, the arrangement could lead to widening its portfolio beyond specialty and high-end automotive carbon fiber applications.

To support the relationship, Teijin will establish the Teijin Composites Application Center, a technical center in the northern part of the United States early next year. In November, Teijin announced it would establish the first pilot plant for fully integrated production of CFRTP components from carbon fiber on the premises of its Matsuyama Factory in Ehime Prefecture, Japan. (Earlier post.)

As carbon fiber is 10 times stronger than regular-grade steel yet only one-quarter of the weight, carbon fiber composites used as automobile components are expected to dramatically reduce vehicle weight. Consumers benefit from lighter weight vehicles with better fuel economy and all the safety benefits that come with vehicles of greater mass.

Teijin’s proprietary breakthrough is its ability to mass-produce carbon fiber-reinforced thermoplastic components with cycle times of less than one minute. Conventional carbon fiber-reinforced composites use thermosetting resins and require a much longer timeframe for molding. This time factor has limited the use of carbon fiber in high-volume vehicles.

Teijin recently received a 2011 Global Automotive Carbon Composites Technology Innovation Award by Frost & Sullivan. The technology also was selected by ICIS Innovation Awards 2011 as the overall winner and the recipient of the Best Product Innovation award.

Increasingly strict global environmental standards and fuel economy regulations have intensified the search to reduce vehicle mass by looking to lightweight materials in place of high-tension steel or aluminum.

The Teijin Group, which has identified automobiles as a key growth market, accelerated the new technology development through collaboration by the Teijin Composites Innovation Center and Toho Tenax Co. Ltd., where the mass-production technology for carbon fiber reinforced plastic components using thermoplastic resin was successfully developed.

The launch of any carbon fiber-intensive vehicle applications resulting from the relationship would be announced closer to market readiness. The agreement does not involve an exchange of equity between the companies.



This is very good news for future electrified vehicles. Lower cost, made in China, composites frames, bodies, wheels and other parts will make ultra light weight future extended range BEVs a reality.

Other manufacturers and countries will have to get on board to compete and maintain their market share.


Fiberforge have been claiming and working on this for years now, apparently it hasn't be widely successful at convincing industrial. Yes let's hope this new project can be more successful.


Tree...demand wasn't there as long as the industry used overpowered ICE gas guzzlers and low cost fuel was available.

With higher fuel price and the very high cost of additional batteries for extended range BEVs, demand for much lighter materials will multiply in the near future.

A wide variety of composites will be on the market within 5 to 10 years. Unit price will drop with improved mass production methods. Fully automated multi-layers 3D printing technology may be used to make low cost high precision composites parts and sub-assemblies.
