  The present invention is an epoxy resin composition characterized by containing component A (epoxy resin containing sulfur atoms in the molecule thereof); and component B (an epoxy resin composition containing an imidazole compound represented by formula (1), and at least one of the following components: component C (an imidazole compound represented by formula (2) below) or component D (an epoxy resin composition having at least one sulfur atom in the molecule. According to the present invention, it is possible to provide an epoxy resin composition which has outstanding stability when stored at room temperature, and which can be heat-cured at a relatively low temperature and over a short time, to give a resin with a high heat resistance when cured. (In formula (1), R1 represents a straight-chain or branched-chain alkyl group having 1 to 5 carbon atoms, or a hydroxymethyl group, R2 represents a straight-chain or branched-chain alkyl group having 1 to 5 carbon atoms, or a hydrogen atom.) (In formula (2), R3 represents an organic group having 1 or more carbon atoms, and R4 to R6 represent hydrogen atoms, methyl groups or ethyl groups.)

  The present invention pertains to a prepreg containing reinforcing fibers and an epoxy resin composition. Said prepreg is sandwiched between dies preheated to 140.degree.C. and pressurized to MPa and held for five minutes at this temperature to obtain a cured article having a G′Tg of at least 150.degree.C. The present invention also pertains to a fiber-reinforced composite material and a method for producing same. According to this invention, it is possible to provide a prepreg which is well suited to press-molding, particularly to high-cycle press-molding. It is also possible to provide a fiber-reinforced composite material which can be heat-cured at a lower temperature and over a shorter time than conventional methods, with which it is possible to minimize excessive flow of resin in hot-press curing, and which is resistant to performance defects such as fiber meandering and defects in surface appearance. A method for producing the same can also be provided.

  本发明涉及一种含有增强纤维和环氧树脂组合物的预浸料。本发明还涉及一种纤维增强复合材料及其生产方法。根据本发明，可以提供一种非常适合压制成型，特别是高循环压制成型的预浸料。本发明还可以提供一种纤维增强复合材料，与传统方法相比，它可以在较低的温度和较短的时间内进行热固化，在热压固化过程中可以最大限度地减少树脂的过度流动，并且可以防止出现纤维蜿蜒和表面外观缺陷等性能缺陷。此外，还可提供生产上述产品的方法。
