LATENT EPOXY RESIN BLENDED SUBSTANCE FOR LIQUID IMPREGNATION METHOD FOR PRODUCING FIBER-REINFORCED COMPOSITE MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide an epoxy resin composition which shows a target flowing curable behavior at an appropriate die temperature of 100-140°C, so as to obtain a high quality composite body.SOLUTION: An epoxy resin composition is formed from a curing agent composition which contains A) at least one epoxy compound, and B): a curing agent composition that is formed from B1) at least one diamine and/or polyamine containing triacetone diamine as a base of 20-40 mass% and B2) at least one diamine and/or polyamine of 60-80 mass%, in which a stoichiometric ratio of the number of A) the epoxy group to the number of the active hydrogen atoms of the functional group of (B1+B2) is 1:0.5 to 1:1, C) at least one curing accelerator, (D) at least one latent curing agent, in some cases, and (E) further an additive substance, in some cases.SELECTED DRAWING: None
