  The present invention provides: an epoxy resin composition which has satisfactory handleability during refrigerated transport, is stable and inhibited from increasing in viscosity for a long period even when held at ordinary temperature, well infiltrates into reinforcing fibers, can be sufficiently rapidly cured at a temperature as high as 180°C, and gives molded objects that can be smoothly demolded in a demolding step after the molding since the resin has sufficiently cured and has high heat resistance imparted thereto; and a fiber-reinforced composite material obtained using the epoxy resin composition. The epoxy resin composition for fiber-reinforced composite materials according to the present invention is an epoxy resin composition for use in producing fiber-reinforced composite materials which comprises an epoxy resin and a hardener, and includes tetraglycidyldiaminodiphenylmethane [A], 4,4'-methylenebis(2-isopropyl-6-methylaniline) [B], and a bisphenol F type epoxy resin [C] in a specific proportion. When the viscosities of the resin at 30°C and 80°C are expressed by η30 and η80 (unit, mPa·s), respectively, then the epoxy resin composition satisfies 200≤η30/η80≤500 and 50≤η80≤180.

  本发明提供了：一种环氧树脂组合物，该组合物在冷藏运输过程中具有令人满意的可操作性，即使在常温下保持稳定并能长期抑制粘度增加，能很好地浸润到增强纤维中，能在高达 180°C 的温度下充分快速地固化，并且由于树脂已充分固化并赋予其较高的耐热性，因此在成型后的脱模步骤中可顺利脱模；以及一种使用该环氧树脂组合物获得的纤维增强复合材料。根据本发明，用于纤维增强复合材料的环氧树脂组合物是一种用于生产纤维增强复合材料的环氧树脂组合物，它由环氧树脂和固化剂组成，并按特定比例包括四raglycidyldaminodiphenylmethane[A]、4,4'-methylenebis(2-isopropyl-6-methylaniline)[B]和双酚 F 型环氧树脂[C]。当树脂在 30°C 和 80°C 时的粘度分别用 η30 和 η80 表示（单位，mPa-s）时，环氧树脂组合物满足 200≤η30/η80≤500 和 50≤η80≤180。
