The oxidation of carbon fiber on the interlaminar shear strength and tribological properties of high-density polyethylene composites

The objective of this work is to improve the interlaminar shear strength and tribological properties of the high-density polyethylene (HDPE) composites by oxidation treatment method of carbon fiber (CF) and ultraviolet irradiation of HDPE. 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.
