SIZING AGENT-COATED REINFORCING FIBERS METHOD FOR PRODUCING SIZING AGENT-COATED REINFORCING FIBERS PREPREG AND FIBER-REINFORCED COMPOSITE MATERIAL

摘要

A sizing agent-coated reinforcing fiber comprising a reinforcing fiber coated with a sizing agent comprising polyrotic acid. The present invention provides a sizing agent-coated reinforcing fiber excellent in mechanical properties when used as a fiber-reinforced composite material, a method for producing the reinforcing fiber, a prepreg using the sizing agent-coated reinforcing fiber, and a fiber-reinforced composite material excellent in mechanical properties.
