摘要
An embodiment of the invention relates to an epoxy resin composition for fiber reinforced composite material having an epoxy resin that is liquid at room temperature (component 1), aromatic polyamine that is liquid at room temperature (component 2) and diaminodiphenylsulfone (component 3). The proportion of component (1) relative to the entire epoxy resin in the composition is 60-100 wt %. The sum of the proportions of components (2) and (3) relative to the entire polyamine in the composition is 70-100 wt %. The proportion of component (3) relative to the entire polyamine in the composition is 25-60 wt %. The stoichiometric ratio of the entire polyamine to the entire epoxy resin in the composition is 0.7-1.3. Additional embodiments of the invention relate to other aspects of the invention.
