采用O-3改性方法对聚丙烯腈基碳纤维进行表面处理。用X射线光电子能谱（XPS）对碳纤维的表面特征进行了表征。采用单纤维拔出试验研究了碳纤维增强尼龙6（CF/PA 6）复合材料的界面性能。结果表明，经O-3处理的碳纤维复合材料的IFSS值比未处理的提高了60%。XPS结果表明，O-3处理增加了碳纤维表面羧基的数量，从而有效地促进了碳纤维与PA 6基体之间的界面粘合。(C)2008年爱思唯尔B。V.保留所有权利。
In this work, O-3 modification method was used for the surface treatment of polyacrylonitrile (PAN)-based carbon fiber. The surface characteristics of carbon fibers were characterized by X-ray photoelectron spectroscopy (XPS). The interfacial properties of carbon fiber-reinforced polyamide 6 (CF/ PA6) composites were investigated by means of the single fiber pull-out tests. As a result, it was found that IFSS values of the composites with O-3 treated carbon fiber are increased by 60% compared to that without treatment. XPS results show that O-3 treatment increases the amount of carboxyl groups on carbon fiber surface, thus the interfacial adhesion between carbon fiber and PA6 matrix is effectively promoted.
