PURPOSE:To enhance the dimensional stability and to reduce the surface roughness by a method wherein an outer-layer sheet is arranged and united on the surface and/or the rear surface of the required number of inner-layer materials via a resin-coated laminated sheet and a prepreg. CONSTITUTION:An outer-layer material is arranged and united on the surface and/or the rear surface of the required number of innerlayer materials via a resin-coated laminated sheet and a prepreg. The resin-coated laminated sheet is obtained by piling up, laminating and shaping the required number of resin- impregnated base materials which are obtained in such a way that a base material of a woven fabric or a nonwoven fabric composed of an inorganic fiber, an organic synthetic fiber or a natural fiber is impregnated with a resin. As the prepreg, a resin-impregnated board to be used as the resin-coated laminated sheet can be used as it is. By this setup, the dimensional stability can be enhanced and the surface roughness can be reduced. |
