PURPOSE:To provide a molding mold, which cures while molding a tubular fiber-reinforced material laminate for a FRP molded form continuously by pultrusion method so as to have a polygonal shape. CONSTITUTION:A groove 24, extending orthogonally to the direction of pultrusion, is provided annularly along the whole periphery of a wall surface at a position entered from the entrance of a molding mold by a predetermined distance while penetrating holes 26A, 26B, penetrating through the wall of the molding mold from the bottom of the groove, are provided. The wall surface of a hollow part from the groove to the entrance of the molding mold is formed so as to be a taper surface whose sectional size of the hollow part is expanded outwardly. A wall surface, forming a corner part extending along the lengthwise direction of the hollow part, is protruded slightly from the wall surface except the area of the corner toward inner direction so as to have a stepped shape. A wall surface, forming the hollow part of the molding mold, is configured so as to be inflated outwardly between positions, circumscribing the corners extending along the neighboring lengthwise directions of the FRP molded forms. |
