PEEK多元复合材料的制备和摩擦学性能

Preparation of PEEK multiple-composite and its tribology property

用模压方法制备了Ekonol/G/MoS2/PEEK多元复合材料,通过摩擦磨损实验方法对材料的摩擦学性能进行了研究,并用SEM对磨损表面进行了观察和分析,在此基础上探讨了复合材料的磨损机理。结果表明:用模压法制备Ekonol/G/MoS2/PEEK合材料是可行的;复合材料与PEEK相比,具有优良的摩擦学性能;随着Ekonol含量的增加,复合材料的磨损机理发生了由犁耕、磨粒、粘着磨损向疲劳磨损的转变。图8,参10。

Ekonol/G/MoS2/PEEK composite was prepared by the compressing model method. The tribology behavior has been investigated by friction and wear experiment. The worn surface of the composite has been studied by the SEM technique,and on the base of it,the wear mechanism has been analyzed. Results show that:it is possible to prepare Ekonol/G/MoS2/PEEK composite by the compressing model method;to compare with pure PEEK,the composite has better tribology properties;with the rising of Ekonol content,the wear mechanism has been changed from abrasive wear,transfer wear to fatigue wear. 8figs. ,10refs.
