ABSTRACT:
The present invention relates to an epoxy resin composition comprising at least (A) an epoxy resin having a cycloalkane ring or cyclohexene ring but having neither aromatic ring nor aminic nitrogen atom, (B) a carboxylic anhydride having no aromatic ring, and (C) an ultraviolet absorbent, wherein a content of component (A) is from 70 to 100 percents by weight based on the total weight of epoxy resins, and a content of component (B) is from 70 to 100 percents by weight based on the total weight of carboxylic anhydrides. By this constitution, the present invention can provide an epoxy resin composition whose cured product excels in mechanical properties and weatherability, and a fiber reinforced composite material having excellent mechanical properties and weatherability.
