Interfacial features of polyamide 6 composites filled with oxidation modified carbon fibres

Abstract

Polyacrylonitrile (PAN)-based carbon fibres were surface treated by ozone modification method and air-oxidation treatment. The interfacial properties of carbon fibre reinforced polyamide 6 (CF/PA6) composites were investigated by means of the single fibre pull-out tests. The surface characteristics of carbon fibres were characterized by X-ray photoelectron spectroscopy (XPS). As a result, it was found that interfacial shear strength values of the composites with ozone-treated carbon fibre are greatly increased. XPS results show that ozone treatment increases the amount of carboxyl groups on the carbon fibre surface, thus the interfacial adhesion between carbon fibre and PA6 matrix is effectively promoted. The effect of surface treatment of carbon fibres on the tribological properties of CF/PA6 composites was comparatively investigated. 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.
