High-strength carbon fiber targets auto applications


Toho Tenax Co., Ltd. (Tokyo), the core company of the Teijin Group's carbon fibers and composites business, has developed a new grade carbon fiber that achieves both high-strength and high-tensile modulus required for aircraft and automotive applications.

Toho Tenax developed Tenax XMS32 with a uniform structure by optimizing the structural design of the polyacrylonitrile (PAN)-based precursor and by optimizing its manufacturing process. Compared to Tenax IMS65, the existing grade carbon fiber that has been mainly used for aircraft applications, Tenax XMS32 reportedly offers 10% greater strength (intensity) and 10% greater tensile modulus. In addition, resin adherence has been significantly improved through new surface-modification technology to refine the chemical characteristics of the carbon fiber's surface and control its smoothness on the nano level.
