Epoxy resin composition, prepreg, and fiber-reinforced composite material |
| abstract |
The present invention provides an epoxy resin composition that serves to produce a cured epoxy resin that simultaneously realizes a high heat resistance, a high elastic modulus, and a low color and to produce a molded article having a good appearance without suffering the formation of white spots on the surface thereof when used as matrix resin in a fiber reinforced composite material. It provides an epoxy resin composition that includes an epoxy resin as component [A] and an imidazole compound as component [B] and meets the undermentioned conditions (a) to (d): (a) it contains an isocyanurate type epoxy resin [A1] as component [A] in an amount of 10 to 40 parts by mass relative to the total quantity of epoxy resins which represents 100 parts by mass, (b) it contains a bisphenol type epoxy resin [A2] as a component [A] in an amount of 40 to 90 parts by mass relative to the total quantity of epoxy resins which represents 100 parts by mass, (c) resin [A2] has an average epoxy equivalent weight of 220 to 500 g/eq, and (d) the content of component [B] is such that the ratio of the number of imidazole groups to the total number of epoxy groups in the epoxy resins is 0.01 to 0.06. |
