Title:
FIBER-REINFORCED COMPOSITE MATERIAL MOLDING APPARATUS AND METHOD FOR MANUFACTURING FIBER-REINFORCED COMPOSITE MATERIAL MOLDED ARTICLE
Document Type and Number:
WIPO Patent Application WO/2019/189369
Kind Code:
A1
Abstract:
Provided are a molding apparatus and method for manufacturing a fiber-reinforced composite material molded article that exhibit superior molded article releasability and superior abrasion resistance in areas of molded surfaces that have been imparted with releasability, and are capable of suppressing reductions in releasability. The fiber-reinforced composite material molding apparatus (101) comprises a mold (130) for molding a fiber-reinforced composite material, in which a fiber-reinforced base material is impregnated with a resin composition, to obtain a fiber-reinforced composite material molded article. Some or all cavity surfaces (113a), (123a) of the mold (13) have a surface free energy of 25.0 mJ/m2 or less as measured via a three-liquid method. It is preferable that some or all of the cavity surfaces (113a), (123a) be injection surfaces through which fluorine and/or silicon are injected.
