Tokyo University, along with composites suppliers Toray Industries, Mitsubishi Rayon, and Toyobo as well as moulder Takagi Seiko, has developed two types of carbon fibre-reinforced thermoplastics (CFRTP) prepegs said to enable weight reduction of between 40% to70% in vehicles. The first is a discontinuous CF-reinforced isotropic prepreg and the second, a continuous CF-reinforced prepreg. Both use PP (polypropylene) but PA (polyamide) can also be employed.
