PEEK复合材料的性能研究

Study on Property of PEEK Composites

对聚醚醚酮 (PEEK)两种复合材料的物理性能、机械性能和摩擦磨损性能进行了测试 ,并利用扫描电镜 (SEM)对其横断面和磨痕表面进行了分析。结果表明 ,灰色PEEK复合材料的摩擦系数为 0 18,比磨损率为 1 79× 10 -6mm3 /(N·m) ;黑色PEEK复合材料的摩擦系数为 0 2 1,比磨损率为 0 61× 10 -6mm3 /(N·m) ,两种复合材料主要受粘着磨损机制控制 。

s The physical characteristics,mechanical properties, friction and wear properties of two kinds of PEEK composite were determimed The morphologies of the wear traces and the microstructure of the cross sections of the composites were analyzed by means of SEM The results showed that the friction coefficient and the wear rate of the gray PEEK composite were respectively 0 18 and 1 79×10 -6 mm 3/(N·m);meanwhile,those of the black PEEK composite were 0 21 and 0 61×10 -6 mm 3/(N·m) respectively The wear of the black PEEK composite was controlled mostly by adhesive mechanism and going with thermoplastic flow
