Improving the interlaminar shear strength (ILSS) of composites is vital for the application
of laminated composites. In this work, graphene oxide (GO) modified short glass fibers
(GO-modified SGFs) was employed to intercalate into glass fiber/epoxy (GF/EP) composites
to improve their ILSS. The effects of GO-modified SGFs and SGFs on the ILSS of composites
were compared. The GF/EP composites were prepared by compression molding. The results
showed that the ILSS of GF/EP composites increased by 12.5% and 18.4% after intercalation
of SGFs and GO-modified SGFs, respectively. GO significantly increased the surface
roughness of SGFs, and improved the interfacial adhesion between SGFs and EP.
