Document Type and Number:
WIPO Patent Application WO/2020/157869
Kind Code:
A1
Abstract:
The present invention relates to an autoclave molding apparatus in which a composite material formed of a fiber base material and a matrix as well as a molding jig are covered by a vacuum bag and molded by heating and pressurizing using steam and provides an autoclave molding apparatus that effectively suppresses composite material temperature overshoot caused by insufficient heat radiation of curing heat in a curing step and obtains a composite material molded article having adequate strength uniformly. Specifically, this autoclave molding apparatus (10) is characterized by a condensed water holding portion (18) for holding condensed water produced by heating being provided on at least part of a vacuum bag (16) and/or a molding jig (14).
