ABSTRACT:
A process for producing a fiber-reinforced resin molding, which includes placing a fiber reinforcement in the cavity of a mold composed of a top force and a bottom force; closing the mold, slanting the mold at an angle of 15.degree. to 90.degree. degrees, rejecting a liquid resin material into the cavity; curing the resin material; and after completion of curing, opening the mold to withdraw the molding therefrom, therein the inside of the cavity is brought into a pressurized state by a pressurized gas during the period after completion of injection of the liquid resin material till gelation of the resin material, and such a pressurized state is maintained until completion of curing.
