Graphene oxide (GO) has been widely used as nano-modifier for improving mechanical properties of polymers. However, the effect of GO size has not been examined yet on interlaminar shear property of glass fiber/GO-modified polymer composites. In order to efficiently enhance the interlaminar shear property of glass fabric/epoxy (GF/epoxy) composites, an epoxy resin was first modified by GO with different sizes and the modified epoxy was then used to manufacture the GF/epoxy composites by a press molding process. Due to its unique wrinkle morphology and functional groups, large GO acts as a 'bridge' to efficiently improve the interfacial adhesion between glass fibers and epoxy resin. The results indicate that at low GO contents (
