Abstract

According to one implementation, a molding equipment of a composite material includes a vessel, a decompression system and a heating medium supply system. The vessel houses a molding target sealed by a sealing object. The decompression system performs bending forming of the molding target and pressurization on the molding target after the bending forming by decompressing a region surrounded by the sealing object in the vessel. The heating medium supply system supplies a heating medium into the vessel. The heating medium is supplied for the bending forming, and heating and curing of the molding target under the pressurization.

First claim
