Title:
METHOD FOR PRODUCING RELEASE FILM AND FIBER-REINFORCED PLASTIC
Document Type and Number:
Japanese Patent JP2014151448
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a release film which is excellent in releasability and heat resistance and is capable of producing a fiber-reinforced plastic with high productivity and handleability even if a prepreg is pressure molded at a high temperature in a state of being interposed between the prepreg and a press surface.SOLUTION: A release layer of a release film is formed by a Calkylated melamine-formaldehyde resin and the centerline average roughness Ra of the surface is adjusted to be 0.012 to 2 μm. The release film further contains a base material layer and the release layer may be formed on at least one surface of the base material layer. The release layer has an average thickness of 0.2 to 5 μm and the base material layer may have an average thickness of 12 to 75 μm. The release film may be a release film for molding a fiber-reinforced plastic by hot-pressing a prepreg in a state of being interposed between the prepreg and a press surface.
