摘要： A method of producing FRP includes disposing a preform made of a reinforcing fiber base material in a cavity of a mold, providing a resin injection path and a suction path that sucks at least air to the mold, and causing resin from the resin injection path to flow in a direction toward the suction path in the cavity to be impregnated into the preform, wherein 1) a high flow resistance region for partially making the resin flowing in the preform hardly flow is formed in the preform itself, 2) a flow front of the resin flowing in the direction toward the suction path through the high flow resistance region is controlled to settle within a permitted region that has been predetermined relative to a shape of a product to be molded, 3) the resin injection path is formed from a runner provided around the preform and the suction path is disposed at a central portion of the preform, and the high flow resistance region is formed at a corresponding part corresponding to a part around the suction path as a high flow resistance region to cause the resin flowing in the preform from a part around the corresponding part toward the corresponding part hardly flow at the corresponding part.

摘要： An RTM method in which a preform formed from a reinforcing fiber substrate is placed in a cavity of a molding die, and resin is injected from a plurality of injection ports into the cavity and impregnated into the preform, includes disposing the plurality of injection ports in first positions in a central section of the cavity corresponding to positions of the preform located in a product area of an article to be finally molded and second positions located in a periphery of the cavity corresponding to positions of the preform outside the product area of the article to be finally molded or corresponding to positions inside the cavity but outside an area of the preform, and causing the timing of closing the injection ports after resin injection to be different from each other between injection ports disposed in the first positions and injection ports disposed in the second positions.
