Abstract:
1. A method of producing a fiber-reinforced plastic comprising: (a) preparing a molding die having a resin filling port at one end portion thereof and a resin suction port at the other end portion thereof, (b) setting a layered body comprising a stack of a plurality of reinforcing fiber base materials in an inner space of the molding die, (c) setting a resin diffusion medium which extends from the resin filling port and is provided along two mutually opposed surfaces of the layered body to supply a resin from the resin filling port to the two mutually opposed surfaces of the layered body, (d) setting a resin suction medium which extends from the resin suction port and is provided only along a side face of the layered body on the suction port side to be in contact with the side face in a state that gas or resin can be sucked from the layered body so that the gas or resin can be moved from the layered body toward the resin suction port, (e) sucking gas in the inner space of the molding die from the resin suction port through the resin suction medium to reduce pressure in the inner space of the molding die, (f) subsequently introducing the resin into the layered body from the resin filling port through the resin diffusion medium, and (g) impregnating the layered body with the resin by moving a part of the resin filled into the layered body toward the resin suction port through the resin suction medium.
