Properties of ultrahigh molecular weight polyethylene (UHMWPE) fiber-reinforced composites depend largely on the interfacial bonding strength between fiber and matrix. In the present work, UHMWPE was irradiation treatment. The existence of functional groups introduced to the fiber surface and the changes of surface roughness were confirmed by Fourier transform infrared (FTIR), X-ray photoelectron spectroscopy (XPS), and scanning electron microscopy (SEM). To evaluate the possible applications of this surface modification of UHMWPE fiber (UF), we examined the mechanical properties as well as the friction and wear performance of thermoplastic polyvinyl chloride (PVC) composites and found that the mechanical properties of PVC composites were all significantly improved. Scanning electron microscope investigation of worn surfaces of PVC composites showed that surface-treated UF/neoprene/PVC (UF/NO/PVC) composite had the strongest interfacial adhesion.
