Abstract
Provided is an epoxy resin composition for fiber-reinforced composite materials, which is improved in toughness necessary for improving the strength of self-adhesion of a matrix resin for use in a prepreg for a face sheet of a honeycomb panel. The epoxy resin composition, which comprises: an epoxy resin (A); a thermoplastic resin (B); fine solid resin particles (C); and a curing agent (D), is characterized in that the epoxy resin composition after being cured has a morphology in which the epoxy resin (A) and the thermoplastic resin (B) form co-continuous phases, and the fine solid resin particles (C) are dispersed in at least the continuous phase of the epoxy resin (A) in the co-continuous phases.
