Method for molding hollow part of composite material and hollow part molding system

Abstract

A method of forming a composite hollow part according to the present disclosure includes: covering a core with a first bag film; forming an intermediate body having a hollow shape by superimposing fibers of the composite material on the first bag film; placing the intermediate body together with the core and the first bag film on an outer mold; covering the outer mold with the second bag film; and demolding the molded composite hollow part by heating the intermediate body and heating the intermediate body after the atmospheric pressure of the outside of the first bag film and the inside of the second bag film is lower than the atmospheric pressure of the outside of the second bag film and the atmospheric pressure of the inside of the first bag film.
