Abstract

PURPOSE: To prevent position shifting of a core material and omit lowering of strength, by making the core material having protrusions on its outer peripheral face at a distance to lie in a molding material when molding a molded article having a core material in a thick wall part.
CONSTITUTION: A molding part 3 which forms a thick wall part is provided in a mold 2. A fibrous reinforcing material 5 is layed along a mold face of the mold 2 and a core material 4 of which a pluraity of protrusions 41 is shaped on its outer peripheral face at a distance is placed on it, and the fibrous reinforcing material 5' is further placed on the core material 4. Then, molds 1, 2 are clamped, a thermosetting resin molding material is poured from a resin pouring port 6 and the fibrous reinforcing material 5, 5' is impregnated. Further, the thermosetting resin molding material is hardened by raising a mold temperature or at an ordinary temperature.
