摘要:
Prepregs, comprising the following components [A], [B] and [C], with the component [C] distributed near either or both of the surface layers without being regularly arranged.[A]: Long reinforcing fibers[B]: A matrix resin[C]: Long thermoplastic resin fibersThe prepregs of the present invention are tacky and drapable, and the composite materials obtained by heating and forming the prepregs are high in heat resistance, and very high in impact resistance and inter-layer toughness. Furthermore, the prepregs are easy to produce and high in their latitude in availability of materials.
