Abstract
PURPOSE: To easily mold the titled light weight box like molded product having an opening part with high rigidity by integrally providing a carbon fiber ribbon to the front and the back surfaces of the opening part periphery of said molded product.
CONSTITUTION: Along the inner surfaces of a metal mold A where the periphery of the opening part of a molded product in the cavity side A1 and the core side A2 is formed, carbon fiber ribbons 1, 2 are set to the total peripheries thereof to carry out molding. The carbon fiber ribbon is set in such a condition that fibers are arranged to the longitudinal direction of the opening part periphery and preliminarily impregnated with a resin. Parts a, b where the carbon fiber ribbons are set are recessed in a notch like form through step parts 3, 4 and pressed to the wall surface of the metal mold by a molten resin stock material and are not released therefrom.
