METHOD FOR PRODUCING FRP

This method for producing FRP in which a preform made of a reinforcing fiber base material is disposed in a cavity of a mold, a resin injection path and a suction path for sucking at least air are provided to the mold, and resin from the resin injection path is made to flow in the direction toward t...

Beschreibung
Zusammenfassung:	This method for producing FRP in which a preform made of a reinforcing fiber base material is disposed in a cavity of a mold, a resin injection path and a suction path for sucking at least air are provided to the mold, and resin from the resin injection path is made to flow in the direction toward the suction path in the cavity to be impregnated into the preform is characterized in that a high flow resistance region for partially making the resin flowing in the preform hardly flow is formed in the preform itself, and the flow front of the resin flowing in the direction toward the suction path through the high flow resistance region is controlled so as to settle within a permitted region that has been predetermined relatively to the shape of a product to be molded. The present invention makes it possible to obtain a molded product having a favorable quality with no air traps.
