Epoxy resin composition, prepreg, and fiber-reinforced composite material |
| abstract |
The present invention addresses the problem of providing an epoxy resin composition excellent in terms of strength, elastic modulus, elastic modulus in wet-heat environments, and heat resistance after moisture absorption, the epoxy resin composition being suitable for use in applications such as prepregs and fiber-reinforced composite materials.nThe epoxy resin composition comprises the following constituent elements [A], [B], and [C] and satisfies the following requirements (1) and (2). [A]: An epoxy resin. [B]: An amine hardener. [C]: A phosphoric ester compound having a molecular weight of 250 or less. (1): To contain the constituent element [C] in an amount of 1-15 parts by mass per 100 parts by mass of the constituent element [A]. (2): The constituent element [A] has an average epoxy equivalent of 160 g/eq or less. |
