The ozone modification method and air-oxidation were used for the surface treatment of polyacrylonitrile-based carbon fibre. The interfacial properties of carbon fibre-reinforced polyamide 6 (CF/PA6) composites were investigated by means of single fibre pull-out tests. It was found that the IFSS values of the composites with ozone treated carbon fibre are increased by 60% compared with that without treatment. The effect of surface treatment of carbon fibres on the tribological properties of CF/PA6 composites was also investigated for comparison. Experimental results revealed that surface treatment can effectively improve the interfacial adhesion between carbon fibre and PA6 matrix. Thus the wear resistance was significantly improved.
