EPOXY RESIN COMPOSITION FOR CARBON FIBER-REINFORCED COMPOSITE MATERIAL, PREPREG, CARBON FIBER-REINFORCED COMPOSITE MATERIAL, AND ELECTRONIC/ELECTRIC PART HOUSING

摘要

PROBLEM TO BE SOLVED: To provide a carbon fiber-reinforced composite material excellent in curability, heat resistance, mechanical characteristics and flame retardancy; to provide an epoxy resin composition suitable for obtaining such carbon fiber-reinforced composite materials; a prepreg and carbon fiber-reinforced composite material; and electronic/electric part housing.;SOLUTION: This epoxy resin composition for carbon fiber-reinforced composite materials comprises an epoxy resin [A] and an organic nitrogen compound curing agent [B], where the component [A] comprises an epoxy resin [A1] represented by formula (II) (provided that n=0 in the formula), an epoxy resin [A2] represented by formula (II) (provided that n=1 in the formula), and an epoxy resin [A3] represented by formula (II) (provided that n≥2 in the formula), so as to satisfy a specified relational formula. In the formula, R₅, R₆ and R₇ each represents a hydrogen atom or a methyl group; and n denotes an integer.;COPYRIGHT: (C)2011,JPO&INPIT
