| 摘要 |
The phenolic resin composition for fiber-reinforced composite materials of the invention comprises at least the following constituent elements A and B of a thermoplastic resin: A: phenolic resin, B: at least one thermoplastic resin selected from polyvinyl formals, polyvinyl acetals, polyvinyl butyrals, polyvinyl pyrrolidones, polyvinyl acetates, polyvinyl alcohols, polyethylene glycols, copolymerized nylons and dimer acid polyamides. The resin composition is filmwise applied to reinforcing fibers, and the resulting film is heated under pressure whereby it is impregnated into the reinforcing fibers to give a prepreg for fiber-reinforced composite materials. |
