PURPOSE: To eliminate troubles in a fabricating process for heat press molding mat consisting of a fibrous material which is used as a core material of an interior automotive trim by hot press molding fabrication.
CONSTITUTION: Thermosetting resin 5 and, if necessary, inorganic fiber and thermoplastic resin 6 are uniformly mixed in natural fiber 2 and synthetic fiber 3 to form a hot press molding mat 7. Then, both surfaces or at least one side surface of the hot press molding mat 7 are heated before hot press molding, and covered with a semi-hardened state resin layer 9 before hot press molding. Since the resin layer 9 consisting of synthetic resin or the like is formed thus on the surface of the hot press molding mat, dust is prevented from being generated in carrying and a hot press molding process. Further since tensile strength is improved with the resin layer 9, the hot press molding mat is excellent in handling.
