PURPOSE:To obtain a light-weight trim material for a motor car by simplifying a manufacturing process and reducing the cost of manufacturing facilities, by a method wherein the process extending to molding of a base material and further to unification of a skin material and base material form vacuum molding of the skin material is performed with the same molding tool without shifting an intermediate molding. CONSTITUTION:A skin material 12 is formed of a thermoplastic plastic sheet, which is heated and in a softened state, by sucking the thermoplastic plastic sheet with vacuum to a mold surface composed of a predetermined form in a molding tool. A matlike fiber-reinforced material 18 is mounted on the skin material 12 of the molding tool through an adhesive agent layer 16 and the matlike fiber-reinforced material 18 is impregnated with polymer raw materials 20 by casting the same into the molding tank. A base material in a state of a mold from is formed by composing and unifying the impregnated and cured high- crosslinking-density polymer and the matlike fiber-reinforced material 18. The base material possesses excellent strength and rigidity as respective strength and rigidity of the high- crosslinking-density polymer and matlike fiber-reinforced material are worked upon by involving with one another. The base material and skin material are turned into a monolithic molding by joining strongly through adhesion at the time of cure of the polymer raw materials and the interposing adhesive agent layer 16.
