Phenol resin compositions for fibre-reinforced composites, prepreg and process for the preparation of the composite materials fäserverstärkten

摘要

A phenolic resin composition for fiber-reinforced composite material, comprising at least the following constituent A and thermoplastic resin B. A : phenolic resin, and B : at least one thermoplastic resin selected from among polyvinyl formal, polyvinyl acetal, polyvinyl butyral, polyvinylpyrrolidone, polyvinyl acetate, polyvinyl alcohol, polyethylene glycol, copolymer nylon, and dimer acid polyamide. A prepreg for fiber-reinforced composite material is produced by coating a film with the resin composition and impregnating the film with reinforcing fibers under heat and pressure.
