CFRP-made car to run at solar race

Teijin Group’s subsidiary Toho Tenax, the core company of the group’s carbon fibres and composites business, and GH Craft, also a member of the Teijin Group, are supporting Japan’s Kogakuin University in developing an advanced solar-powered car made with carbon-fibre-reinforced plastic (CFRP). The vehicle will be entered in Bridgestone World Solar Challenge, the world’s biggest solar car race, which will take place in Australia from October 18 to 25.

Teijin supplied the university with ultra-lightweight fabric made with Tenax carbon fibre, which was used to design and fabricate the racing vehicle’s 2-seater body. GH Craft has been involved from the concept stage in developing the all-carbon composite body. With Tenax, the bodyweight is reduced by 55 kg, but still ensures practicality and safety, as well as the tensile modulus (rigidity) and tenacity (strength) needed to withstand endurance racing, says Teijin.

Toho Tenax, together with Sakai Ovex, developed carbon fibre fabric as thin as 0.06 mm in 2010. The CFRP produced with this material was used to fabricate the car body.

GH Craft, founded in 1972, is engaged in all stages of composite structure fabrication, including design, moulding and structural evaluation. It develops CFRP composite structures for transportation, including in the automotive, marine, rail and aerospace industries, as well as wind power generation equipment in the energy field.

In addition to thermoset CFRP developed by Toho Tenax and GH Craft, Teijin is researching and developing thermoplastic CFRP at its Teijin Composites Innovation Centre. Teijin markets thermoset and thermoplastic CFRP applications through its Automotive Business Development Group.

Going forward, Teijin says it will continue to leverage its all-round capabilities to develop advanced CFRP solutions for automotive purposes, one of many ways it says it is establishing its position as a global leader in carbon fibre and composites.
