Abstract: The present invention relates to a method for manufacturing fiber-reinforced plastic products. This method comprises the following steps of: preparing a fiber preform (2) on a mold (1); disposing first (4a) and second (4b) flow meshes and first (3a) and second (3b) demolding cloths; sealing the fiber preform to form a vacuum system by pumping; penetrating the resin through the first peel ply via the first flow mesh and impregnates the fiber preform from bottom to top; penetrating the resin through the second peel ply via the second flow mesh and impregnates the fiber preform from top to bottom; and attaining a resin-impregnated fiber perform and finally attaining fiber-reinforced plastic products. The invention is characterized in that : a first film (5a) is disposed on a resin-injection side of the fiber perform to cover the first injection port (8a), the first demolding cloth, the first flow mesh and at least a part of the fiber perform, after the resin is supplied to the first flow mesh, the resin is supplied to the second flow mesh when the resin over said fiber perform flows beyond the area covered by the first film.
