Abstract
The present invention provides: a curable composition characterized by comprising an epoxy compound (A), one or more amine compounds (B), and an acrylic resin (C), the amine compounds (B) comprising an N-(aminoalkyl)piperazine compound (B1) as an essential ingredient; a cured object; a fiber-reinforced composite material; a molded fiber-reinforced-resin article; and a production method for the molded fiber-reinforced-resin article. The curable composition can form cured objects excellent in terms of mechanical strength, heat resistance, etc. and hence is suitable for use in producing fiber-reinforced composite materials, molded fiber-reinforced-resin articles, etc.
Description
technical field [0001] The present invention relates to a curable composition excellent in mechanical strength, heat resistance, etc. in a cured product, a cured product thereof, a fiber-reinforced composite material, a fiber-reinforced resin molded article, and a method for producing a fiber-reinforced resin molded article. Background technique [0002] Fiber-reinforced resin molded products are attracting attention due to their light weight and excellent mechanical strength, and they are increasingly used in various structural applications, including shells and various components of automobiles, aircraft, ships, etc. Fiber-reinforced resin molded products can be produced by molding fiber-reinforced composite materials using molding methods such as fiber winding, press molding, hand lay-up, pultrusion, and RTM. [0003] In the aforementioned fiber-reinforced composite material, reinforcing fibers are impregnated with a resin. For resins used in fiber-reinforced composite m...
