Problems solved by technology
However, when the above method is used, there are problems that the release agent transfers to the surface of the molded product, degrading the appearance and quality, and when the adhesive or paint is applied to the molded product, their adhesiveness decreases.
However, when a release agent is added to a fiber-reinforced composite material, the curability and heat resistance of the resin composition decrease

Embodiment 1
[0141] The processed surface of a mirror-finished metal plate (SUS304, thickness 6 mm, 100 mm × 100 mm square) was subjected to surface treatment by implanting fluorine into a chromium nitride film by a plasma-assisted sputtering (PBS) process (TS Nanocoat) ( Surface treatment A1).
Embodiment 2
[0143] Surface treatment (surface treatment B) by CERTESS N-S (registered trademark) coating (manufactured by TS Nanocoat) was performed on the machined surface of a mirror-finished metal plate (SUS304, thickness 6 mm, 100 mm×100 mm square).
Embodiment 3
[0145] The processed surface of a mirror-finished metal plate (SUS304, thickness 6 mm, 100 mm × 100 mm square) was subjected to surface treatment by implanting fluorine into a chromium nitride film by a plasma-assisted sputtering (PBS) process (TS Nanocoat) ( Surface treatment A2).

Abstract
Provided are a molding apparatus and method for manufacturing a fiber-reinforced composite material molded article that exhibits superior molded article releasability and superior abrasion resistancein 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 materialmolded article. Some or all cavity surfaces (113a), (123a) of the mold (13) have a surface free energy of 25.0 mJ / m<2> or less as measured via a three-liquid method. It is preferable that some or allof the cavity surfaces (113a), (123a) be injection surfaces through which fluorine and / or silicon are injected.
Description
technical field [0001] The present invention relates to a molding device of fiber-reinforced composite materials and a method for manufacturing molded articles of fiber-reinforced composite materials. [0002] This application claims priority based on Japanese Patent Application No. 2018-061742 filed in Japan on March 28, 2018, and the contents thereof are incorporated herein. Background technique [0003] For fiber-reinforced composite materials as intermediate materials for lightweight and highly rigid fiber-reinforced composite molded articles, there are known prepregs in which continuous fibers made of carbon fibers are impregnated with a resin composition, dispersed with A sheet molding compound (SMC) or a punched sheet impregnated with a resin composition in a fiber base material of short fibers formed of carbon fibers. [0004] As a method of manufacturing fiber-reinforced composite molded articles, a method of laminating a plurality of prepregs and molding them in a...
