PURPOSE:To simplify a molding process and to obtain a composite material having excellent strength by a method wherein a fiber material is positioned in a mold to be impregnated with a liquid resin material and the impregnated one is cured to form a thermoplastic reinforced resin which is, in turn, used to cover the outer periphery of a pad material. CONSTITUTION:A projection part 5c and a butt surface 6c are mutually brought to a contact state so as to hold a protruding part 4a therebetween and the protruding part 4a is positioned to be held between the projection part 5c and the butt surface 6c. Subsequently, a liquid thermoplastic resin material 11 is injected from a resin injection hole 7 and infiltrated in glass fiber materials 4 are changed to thermoplastic reinforced resins 3 by the impregnation with the thermoplastic resin material 11. Further, the upper and lower thermoplastic reinforced resins 3 and a pad material are mutually bonded and integrated by the impregnation with the thermoplastic resin material 11 and the whole is taken out of a mold to obtain a composite material 1. |
