Title: EPOXY RESIN COMPOSITION AND FIBER-REINFORCED COMPOSITE MATERIAL
Abstract:
Provided are: an epoxy resin composition which has low viscosity and sufficient pot life and enables a cured product thereof to exhibit high heat resistance and fracture toughness; a cured product having the above-described properties; a fiber-reinforced composite material; a fiber-reinforced resin molded article; and a method for producing a fiber-reinforced resin molded article. An epoxy resin composition which is characterized by containing (a) an epoxy resin having an average number of functional groups of 1.5-2.2, (b) an acid anhydride, (c) a polyol compound containing two or more alcoholic hydroxyl groups in each molecule, while having a hydroxyl equivalent of from 30 g/eq to 650 g/eq, and (d) a curing accelerator.
