Teijin group cooperates with Kawasaki to develop carbon fiber reinforced leaf spring

Teijin company, founded in 1918, is the first company in Japan to produce man-made fibers. At present, it is still in the leading position in synthetic fiber production and technology. Toho Tenax, which specializes in the research and development of carbon fiber and composite materials of Teijin group, announced on December 21 that it agreed to jointly develop carbon fiber reinforced composite (CFRP) leaf springs with Kawasaki Heavy Industry Co., Ltd. during this period, which can be produced in large quantities and applied to rail vehicles. The leaf spring was first developed in 2013 and has been applied in Kawasaki's new generation rail car efwing

toho Tenax will help build a complete system, covering from carbon fiber precursor to finished carbon fiber composite leaf spring. The new mass production system will enable efwing to open the global sales market

"relying on its high-performance carbon fiber technology, Teijin group and Kawasaki heavy industry jointly developed carbon fiber reinforced plastic (CFRP) leaf springs that destroy its tightness, which will accelerate the development of its downstream strategy", said Takashi Yoshino, CEO of Teijin group. Yoshino is also the general manager of the group's carbon fiber and composite business department and the chairman of Toho Tenax. "Diren group has been persistently focusing on innovative transportation solutions to expand its carbon fiber and composite materials, which is certainly an effective material business, and the carbon fiber business is also the key to the downstream development strategy of Diren group."

the frame and coil spring of traditional railway freight cars are made by MTR, but efwing is the first rail vehicle in the world to use carbon fiber reinforced plastic to make these components and simplify the processing technology. Lighter materials and simplified design help to reduce the weight of the frame. Each vehicle can reduce at least 900 kg, which will effectively improve the cost-effectiveness of operation, reduce carbon dioxide emissions, and reduce the risk of wheel derailment
