Abstract
The resin-reinforcing fiber of the preset invention is a fiber surface-treated with an epoxidized polydiene resin. The fiber is preferably carbon fiber or glass fiber. The fiber-reinforced resin composite material of the present invention comprises the resin-reinforcing fiber and a matrix resin. The matrix resin is preferably an epoxy thermosetting resin. The resin-reinforcing fiber of the present invention can improve the absorbed energy up to the maximum load (elastic energy) of a fiber-reinforced resin composite material and the absorbed energy after the maximum load (propagation energy) thereof at the same time.
Claims
exact text as granted — not AI-modified1 . A resin-reinforcing fiber in which a fiber is surface-treated with an epoxidized polydiene resin.
