Abstract:
1. A method of molding a flanged fiber-reinforced resin hollow part, the method being adapted to mold a fiber-reinforced resin hollow part with a flange portion integrally formed at one end thereof by an internal-pressure molding method, comprising: a step of connecting a second core to one end of a preformed hollow resin core, wherein the preformed hollow resin core is closed at the one end and open at an opposite end; a step of forming a hollow laminate by laminating at least reinforced fibers on a circumference of the hollow resin core and the second core; a step of pulling the second core out from the hollow laminate, and pressing inwardly together a region of the hollow laminate, from which the second core has been pulled out, into a flattened shape to form a flange portion, so as to form a hollow laminate with the flange portion formed at one end thereof; a step of disposing the hollow laminate within a shaping mold; and a step of shaping the hollow laminate with the flange portion disposed within the shaping mold into a flanged fiber-reinforced resin hollow part by an internal-pressure molding method.
