Abstract
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.
