Abstract
It is an object of the present invention to improve drawbacks in conventional technology and provide a fiber-reinforced composite material having both an excellent static strength property and impact resistance, and an epoxy resin composition for obtaining the fiber-reinforced composite material. More particularly, it is the object of the present invention to provide the epoxy resin composition that gives a cured material having a high elastic modulus, a high heat resistance, a high plastic deformation capacity and a high toughness.The epoxy resin composition containing following [A] to [D], a prepreg obtained by impregnating a fiber substrate with the epoxy resin composition, a fiber-reinforced composite material obtained by curing the prepreg and a tubular body thereof.
