WIPO Patent Application WO/2019/244829

A1

The purpose of the present invention is to provide: an epoxy resin composition capable of giving cured resins which combine flexural modulus with flexural strain on a high level and have excellent heat resistance; a prepreg comprising the epoxy resin composition and reinforcing fibers; and a fiber-reinforced composite material obtained by curing the prepreg and excellent especially in terms of 0° and 90° bending strength. An embodiment of the epoxy resin composition of the present invention for achieving such purpose is an epoxy resin composition which comprises the following components [A], [B], and [C] and satisfies a specific requirement. Component [A]: a trifunctional amine type epoxy resin. Component [B]: a bisphenol F type epoxy resin which is solid at 25°C. Component [C]: an aromatic amine compound.
