ABSTRACT:
A resin composition especially suited to the resin transfer molding and wet filament winding processes is composed of epoxide compounds and one or more aromatic amine hardeners wherein the blend of epoxide compounds is (i) a diglycidyl ether of the reaction product of a bisphenol and a blend of (a) a diglycidyl ether of bisphenol A other than that of (i) and (b) a halohydrin having about two epoxy groups per molecule, (ii) a copolymer of ethyl hexyl acrylate and glycidyl methacrylate and (iii) a neopentyl glycol digylcidyl ether. This composition has a low viscosity, and when cured, exhibits high toughness and mechanical strengths useful in making high performance composites.
