Teijin says that this is the world’s first use of CFRTP for structural parts in a high-volume production vehicle.
Sereebo will be used to manufacture the optional CarbonPro pickup box jointly developed by Teijin and GM for the GMC Sierra Denali 1500 and GMC Sierra AT4 1500. Specifically, the pickup box’s inner headboard, side and floor panels will be made with Sereebo. Following production startup in early June, GMC Sierra CarbonProEditions for both vehicles will begin appearing at select GMC dealerships in the US this summer. The CarbonPro panels will be produced at Continental Structural Plastics’ Huntington, Indiana, US manufacturing facility.
Sereebo used for CarbonPro contains randomly-orientated, isotropic carbon fibre in a polyamide matrix resin. Manufactured using the world’s first mass-production technology for CFRTP, the moulding time for Sereebo is approximately one minute, which is significantly shorter than the moulding time for conventional carbon fibre reinforced thermoset plastics (CFRP). Compared to steel, CarbonPro is 40 percent lighter, offers 10 times greater impact resistance, is more corrosion-resistant, and is even more readily recyclable. Finally, because of its material characteristics, Sereebo offers extended design flexibility and freedom, which allowed GM engineers to mould in many of the unique features of the CarbonPro box.
Teijin has been developing leading-edge composite product technologies and applications since establishing the Teijin Composites Innovation Centre in 2008. In 2011 the company developed the world’s first mass-production technology for CFRTP, realising a production interval (takt) time of just one minute. Teijin subsequently established a technical facility in the US and a pilot plant for fully integrated production of CFRTP in Japan. Since branding its CFRTP product as Sereebo in 2012, Teijin developed high-volume production methods in collaboration with domestic and international partners, including GM. After acquiring CSP, a global leader in automotive lightweight composite technologies in 2017, Teijin established an organisational framework for composites production, sales and evaluation in North America. GM’s adoption of Sereebofor CarbonPro is a momentous step forward for CFRTP’s use in high-volume vehicles.
Teijin is expanding its product portfolio ranging from materials to component design, as well as its global supply chain, in an effort to help automakers reduce vehicle weights. Teijin also aims to become an automotive solution provider by expanding its offerings beyond carbon fibre and glass fibre materials, for which the company is actively collaborating with other materials manufacturers. The automotive composite products business of the Teijin Group is targeting annual sales of USD 2.0 billion by 2030.
