EPOXY RESIN COMPOSITION FOR CARBON-FIBER-REINFORCED COMPOSITE MATERIAL RESIN SHEET PREPREG CARBON-FIBER-REINFORCED COMPOSITE MATERIAL

摘要

The present invention, when used as an epoxy resin composition of a carbon fiber reinforced composite material, a carbon fiber reinforced composite material that can provide a carbon fiber reinforced composite material exhibiting high heat resistance, dimensional stability, and high toughness and rigidity as a cured product An object of the present invention is to provide an epoxy resin composition and an excellent prepreg, a resin sheet, and a carbon fiber reinforced composite material using the resin composition. The epoxy resin composition for carbon fiber reinforced composite materials of the present invention contains an epoxy resin represented by the following general formula (1) and a curing agent as essential components. (Wherein, the ratio of (a) to (b) is (a)/(b) = 1 to 3. G represents a glycidyl group. n is the number of repetitions and is 0 to 5.)
