▎ 摘　　要

The objective of this work is to improve the interlaminar shear strength and tribological properties of the PA 6 composites by graphene oxide-treated carbon fiber (CF) and ultraviolet irradiation of PA 6. The morphologies of untreated and treated CFs were characterized by X-ray photoelectron spectroscopy. Surface analysis showed that after treatment, the surface of CFs chemisorbed oxygen-containing groups; active carbon atom, the surface roughness, and wetting ability were increased. The results show that the treated CF composites can possess excellent interfacial properties and tribological properties accordingly after treatment. Copyright (c) 2017 John Wiley & Sons, Ltd.
