Epoxy acrylate resin has the advantages of toughness and corrosion resistance as a matrix resin of composites. Also it has been recognized as a compatible resin system for the matrix of CF/GF hybrid composites. In this study, some epoxy acrylates were synthesized from bis-phenolic epoxy oligomers and methyl methacrylic acid and were modified with diisocianates to study the effect of chemical composition of resin systems on composite properties. With increasing epoxy oligomer's n value, interlaminar strength increased in CFRP and CF/GF hybrid laminates. In addition, some peculiar chemical reaction seemed to occur at the interface of carbon fiber with isocianate modificated resin systems, which indicates a possibility of creating a new high strength CF-composite from unsaturated resin systems.
