稀土对玻璃纤维填充金属-塑料多层复合材料抗冲击磨损性能的影响

研究了稀土元素处理玻璃纤维填充金属－塑料多层复合材料在冲击载荷、干摩擦条件下的摩擦和磨损性能，并利用扫描电子显微镜（SEM）对磨损表面进行了观察和分析，结果表明，用稀土表面改性剂处理玻璃纤维表面，可以提高玻璃纤维与聚四氟乙烯之间的界面结合力，改善复合材料的界面性能，并有利于在偶件表面形成分布均匀、结合强度高的转移膜，使复合材料与偶件表面之间的对摩减轻，大幅度地降低了复合材料的磨损，从而使复合材料具有优良的摩擦性能和抗冲击磨损性能。

Improvement of Impact Wear-Resistance of Metal-Plastic Multilayer Composites Filled with Rare Earth-treated Glass Fiber

The friction and wear properties of metal plastic multilayer composites were investigated under impact load and dry friction conditions. The composites were filled with glass fiber with or without rare earth treatment. The worn surfaces were observed and analyzed by scanning electron microscopy (SEM). It is shown that rare earth elements acting as surface modifier of the glass fiber can enhance the interfacial adhesion between the glass fiber and polytetrafluoroethylene (PTFE), and promote the interface properties of the composites. This helps to form a uniformly distributed and high adhesive transfer film on the counterface and reduce the friction between the composite and the counterface. As a result, the wear of composite is greatly reduced. The composite exhibits excellent friction properties and impact wear resistance.
