Kevlar fiber was modified by means of the anionic graft of nylon 6 oligomer.Nylon 6/modified Kevlar fiber(PA6/KF1) composites were prepared by extrusion and injection process.Both ESEM and XPS measurements proved that the nylon 6 oligomer was grafted onto the surface of Kevlar fiber.The mechanical properties,fracture morphologies and fracture mechanism of PA6/KF0 and PA6/KF1 composites were compared and studied.After being treated,the composites' tensile strength,flexural strength and flexural modulus were increased by 20.69%,12.26% and 14.23% respectively,however,the impact strength declined by 8.2%.The adhesive nylon 6 on the PA6/KF1 composites was more than that on the PA6/KF0 composites when the composites were destroyed,and the failure morphology of PA6/KF1 composites was non-interfacial destruction.
