Toho Tenax Co. Ltd. (Tokyo, Japan) the core company of the Teijin Group’s carbon fibers and composites business, announced on Nov. 6 its development of a new prepreg that offers super-high-heat and oxidation resistance, suited to automotive and aircraft engine compartments. The new bismaleimide resin pre-impregnated prepreg reportedly does not reach glass-transition below 320°C/608°F. It also maintains oxidation resistance without heat cracks under continuous use in the range of upper 200°C/392°F degrees. Conventional bismaleimide resin-impregnated prepreg has been used in high-temperature applications such as automotive and motorbike engine compartments, but it degrades due to resin oxidation after continuous use at high temperatures and forms microcracks after repeated heat expansion and contraction. To further expand its carbon fibers and composites business, Toho Tenax says it also intends to develop carbon fiber composite technologies to explore new applications in downstream industries, including materials for structural parts.
