Abstract
Provided is a method capable of easily and inexpensively molding a flanged fiber-reinforced resin hollow part with a non-uniform cross-section and a bent portion with a sufficiently reduced weight and substantially uniform thickness. To this end, a hollow laminate () is formed by laminating reinforced fibers () and matrix resin () on the circumference of a coupled body of a preformed hollow resin core () and a second core (). The second core () is pulled out from the hollow laminate () and a region of the hollow laminate (), from the second core () was pulled out, is pressed into a flange-shaped portion (). A pressurization bag () is inserted into the hollow resin core () and it is then disposed within a shaping mold (). Heat is applied while at the same time applying pressure to the inside of the pressurization bag () in the hollow laminate () disposed within the shaping mold, whereby the resin and the reinforced fibers are combined, inclusive of the flange-shaped portion ().
