Japanese fibre producer, Toray Industries said its carbon fibre material has been adopted by Toyota Motor for its Mirai, a fuel cell vehicle to be introduced in December this year.

Toyota has used Toray’s carbon fibre reinforced thermoplastic (CFRTP) developed for automobile structural parts, carbon paper for electrode substrate of fuel cell stack and high strength carbon fibre for high pressure hydrogen tank.

Toray said, the CFRTP has been is used in a part called ‘Stack Frame’, which is equivalent to the vehicle floor.

Toray, together with Toyota, developed CFRTP which achieves short press moulding time suitable for mass production by leveraging the characteristics of thermoplastic.

According to Toray, it is the first time in the world that CFRTP has been used in the structural part of a mass production vehicle.

The carbon paper, which Toray has been developing for more than 30 years, was adopted for the electrode substrate of fuel cell stack, which is the heart of a fuel cell vehicle.

“This carbon paper meets prescribed properties such as gas diffusion and durability and contributes to improvement of the fuel cell stack performance and space saving,” Toray informed.

Further, Mirai’s high pressure hydrogen tank uses the high strength carbon fibre, Toray has developed specifically for high pressure hydrogen tanks, which satisfies the safety, strength and light weight requirements of such tanks.

Toray also said it will focus on expansion of its advanced material business in the growing markets to achieve its corporate philosophy under the Green Innovation Business Expansion Project.

“Toray Group will promote energy savings by reducing the weight of aircrafts and automobiles by using carbon fibre composite materials,” the fibre producer added. (AR)
