| Abstract: | In this work, ozone modification method and air-oxidation are used for the surface treatment of polyacrylonitrile(PAN)-based carbon fiber. The
surface characteristics of carbon fibers are characterized by X-ray
photoelectron spectroscopy (XPS). The interfacial properties of carbon fiber
reinforced polyamide 6 (CF/PA6) composites are investigated by means of the
single fiber pull-out tests. As a result, it is found that IFSS values of the composites with ozone treated carbon fiber are increased by 60% compared to that
without treatment. XPS results show that ozone
treatment increases the amount of carboxyl groups on carbon fiber surface, thus
the interfacial adhesion between carbon fiber and PA6 matrix is effectively
promoted. The effect of
surface treatment of carbon fibers on the tribological properties of CF/PA6 composites is investigated. Experimental results reveal that surface treatment can
effectively improve the interfacial adhesion between carbon fiber and PA6
matrix. Thus, the wear resistance is significantly improved. |
