摘要： An epoxy resin composition comprises components [A] to [C]. The component [C] is a component [c1] or [c2] and the rubbery state elastic modulus of a cured article produced by curing the epoxy resin composition in a dynamic viscoelasticity evaluation is 10 MPa or less. Component[A] is a phenyl glycidyl ether substituted by a tert-butyl group, a sec-butyl group, an isopropyl group or a phenyl group. Component [B] is a bifunctional or higher aromatic epoxy resin. Component [C] is a curing agent selected from component [c1], which is an acid anhydride-type curing agent and component [c2], which is an aliphatic amine-type curing agent.

摘要： Provided is a method for producing a fiber-reinforced composite material exhibiting high heat resistance and excellent appearance quality. It is a method for producing a fiber-reinforced composite material, which includes disposing a prepreg containing a reinforced fiber being impregnated with an epoxy resin composition in a mold, pressurizing and heating the prepreg at 0.2 to 2.5 MPa and 130° C. to 200° C. as primary curing, and then further heating the prepreg at 210° C. to 270° C. for 10 minutes or more as secondary curing.

摘要： One purpose of the present invention is to provide an epoxy resin composition which is for obtaining a fiber-reinforced composite material that combines heat resistance with tensile strength on a high level. The other purpose is to provide: a fiber-reinforced composite material obtained using this epoxy resin composition; and a molded article and a pressure vessel both containing the fiber-reinforced composite material. The present invention has the following configuration in order to achieve the above purposes. Namely, the epoxy resin composition includes the constituent element [A]: An epoxy resin including an aromatic ring and having a functionality of 2 or higher and the following constituent element [B]: An amine-based hardener or an acid anhydride-based hardener, and is characterized in that a cured object obtained by curing the epoxy resin composition has a rubber-state modulus of 10 MPa or less when evaluated for dynamic viscoelasticity and the cured object has a glass transition temperature of 95° C. or higher.
