PURPOSE:To provide a matter which is light in weight and superior in mechanical strength though it is a fiber-reinforced resin foam molded body, possesses high surface smoothness and is comparatively thick. CONSTITUTION:A boardlike fiber-reinforced layer 3 is formed by laying threadlike fibers 2, 2... between both fiber layers 1, 1 which are comprised of woven fabric or nonwoven fabric arranged up and down, a main body layer 19 comprised of a thermosetting resin foam is formed in the reinforced layer 3 and a surface layer 18 comprised of the thermosetting resin is formed. Thereby, the threadlike fibers 2 are interposed also in the direction of a thickness of the fiber-reinforced layer 3, directional properties of mechanical strength is improved, width thickening and weight reducing are performed by the main body layer 19 comprised of the foam, foaming pressure at the time of forming of the main body layer 19 within a setting mold is used even at the time of molding, the surface layer 18 is forced to press against an inner wall surface of the mold and the inner wall surface can be made to provide with smoothness of the surface layer 18. |
