ABSTRACT:
Described are novel thermosetting epoxy resin compositions suitable for making cured resins, prepregs and stiff, tough thermoset composites. The thermosetting compositions comprise a polyepoxide component, an amine hardner and a specified amount of certain aromatic oligomers containing functional groups which are reactive with the polyepoxide and/or hardener under curing conditions for the composition. The cured resins have a multiphase morphology which comprises at least one glassy continuous phase and at least one glassy discontinuous phase and have a fracture toughness, K.sub.IC, of at least 1.0 MPam.sup.1/2.
