The present invention is excellent in viscosity stability at low temperature (40 ° C.) of the epoxy resin composition after mixed preparation, maintains low viscosity at the time of injection into reinforcing fiber and is excellent in impregnating property, and resin viscosity after impregnation is moderate. Provided are a two-pack epoxy resin composition in which resin flow is controlled by rising, and a fiber-reinforced composite material using the same. The two-component epoxy resin composition for fiber reinforced composite materials of the present invention comprises the following components [A] to [E], and a total of 100 of components [A], components [B] and [C]. The content of the component [A] is 5 to 45 parts by mass, the content of the component [B] is 5 to 50 parts by mass, and the content of the component [C] is It is a two-pack type epoxy resin composition for fiber reinforced composite materials whose content is 5 to 50 parts by mass. Component [A]: alicyclic epoxy resin Component [B]: aliphatic epoxy resin Component [C]: bisphenol type epoxy resin Component [D]: acid anhydride Component [E]: quaternary ammonium A compound selected from the group consisting of salts, quaternary phosphonium salts and imidazolium salts. |
