Abstract
Free-radical curable amino vinyl ester resin binder compositions for fiber reinforced composite materials with improved interlaminar shear strength and accelerated cure rate. The composition comprises about 80 to about 20 weight percent of amino vinyl prepolymer and about 20 to about 80 weight percent of a crosslinkable diluent, wherein the prepolymer consists essentially of the reaction product of epoxy-amino alcohol adduct and unsaturated monomer having a terminal vinyl group and a hydroxy reactive functionality capable of reacting with the hydroxyl groups of the adduct. The polyepoxide and amino alcohol, preferably a diethanol amine, are reacted in a ratio of about 1:1-1.2 equivalents of epoxide to amine groups, so as to react essentially all of the epoxide groups. Subsequently, between about 0.3-1.0 of the hydroxyl groups of the adduct are reacted with the vinyl monomer.
