Toray develops highly shock-absorbent FRP for commercial automotive use from 2020

Toray has developed a fiber-reinforced plastic with a high shock absorbency. By adding a polyrotaxane, which has mobile molecular bonds, to a polyamide resin, Toray has succeeded in giving FRP “tenacity,” enabling it to disperse stress, while maintaining strength and rigidity. In impact tests that assumed its use as an automotive structural material, the new FRP absorbed approximately eight times more energy than conventional polyamide, and four times more than glass-fiber-reinforced polyamide. In addition, the elongation at fracture recorded exceeded 15%. Toray aims to release the product commercially in 2020, as a shock-absorbing material for automotive use.
