    Abstract: Provided are a fiber-reinforced composite molded article prepared by heat-curing, as a molding material of a fiber-reinforced resin material, a resin composition to which an internal mold release agent is added, the fiber-reinforced composite molded article being capable of effectively producing mold releasability even with a small amount of the mold release agent added, and being capable of achieving high productivity, and a method of forming the fiber-reinforced composite molded article. A fiber-reinforced composite molded article prepared by curing reinforcing fibers and a resin composition, the resin composition including an internal mold release agent, wherein the value obtained by normalizing a Poisson-corrected ion intensity derived from the internal mold release agent detected on the surface of the fiber-reinforced composite molded article, by the Poisson-corrected gross positive secondary ion intensity detected in the predetermined area is higher than 0.1, and a molding method therefor.

    Abstract: A release agent for plastic contains the following components (A) to (E) and has an average particle size of 200 nm or less: (A) 100 parts by mass of an organopolysiloxane having a viscosity at 25° C. of 100 to 100,000 mm2/s; (B) 0.1 to 15.0 parts by mass of one or more anionic surfactants; (C) 1.0 to 30.0 parts by mass of a polyoxyethylene alkyl ether; (D) 0.5 to 15.0 parts by mass of a polyoxyethylene sorbitan fatty acid ester; and (E) 50 to 100,000 parts by mass of water. The release agent is an organopolysiloxane emulsion having excellent dilution stability and mechanical stability and favorable wettability, and hardly cracking plastic.

    Abstract: A method of preparing an aluminum mold for injection molding is provided, the method comprises the steps of providing an aluminum mold having a least one surface, subjecting the at least one surface to a gas or liquid phase silane to thereby form an anti-stiction coating, the anti-stiction coating comprising a chemically bonded monolayer of silane compounds on the at least one surface wherein the silane is a halogenated silane. The at least one surface coated with the anti-stiction coating may be configured to withstand an injection molding process at a pressure above 100 MPa. Furthermore, a mold having at least one closed cavity is provided, at least one surface of the at least one cavity being an aluminium surface coated with a silane based coating layer. The resistance of the coated aluminium mold is significantly improved by applying a silane-based coating layer.

    Abstract: The process for molding a thermoset sheet-molding composition or bulk-molding composition is provided that includes the exposure of a mold surface to a silsesquioxane monomer or pre-polymer material under conditions to induce polymerization of said material or said monomer to form a mold release coating on the surface. The thermoset sheet-molding composition or bulk-molding composition is then injected into the mold and into contact with said coating under conditions to cure the composition to form an article.
