Toho Tenax reports that the prepreg cures in 3 minutes at 150°C, resulting is an increase in production efficiency "by a factor of many dozens," which will allow the company to raise annual production capacity to 50,000 CFRP parts.
The prepreg can be formed at a low pressure of around 0.5 MPa. The prepreg was initally developed for automotive applications, but Toho Tenax will also explore opportunities in the aerospace, sports, and other markets.
A flame-resistant version now under development is expected to further expand applications to consumer electronics and other sectors.
Toho Tenax Co Ltd is the core company of Teijin Group’s carbon fibre and composites busines.
