Development of low friction and high wear resistant polymercomposites filled with hard porous carbon particulate

本文研制了以RB陶瓷颗粒填充的新型聚合物复合材料（聚合物/RB陶瓷复合材料），并对其摩擦磨损性能进行了实验研究。每种树脂的RB陶瓷颗粒重量分数均大于50 wt%。在干润滑和油润滑条件下，聚合物/RB陶瓷复合材料比纯树脂（PA66、PA11、PBT、POM、PP）具有更低的摩擦和磨损。特别是，与纯树脂相比，新开发的复合材料在干燥条件下（减少67-98%）或油润滑条件下（减少68-99%）的比磨损率显著降低。

In this study, new polymer composites filled with RB ceramics particulate (polymer/RB ceramics composites) was developed, and their friction and wear properties were experimentally investigated. The weight fraction of RB ceramics particulate was greater than 50 wt% for each resin. The polymer/RB ceramics composites showed lower friction and lower wear than neat resins (PA66, PA11, PBT, POM, PP) under dry and oil lubricated conditions. Particularly, a remarkable reduction of specific wear rate was obtained for the newly developed composites as compared with the neat resins under dry condition (67-98% reduction) or oil lubricated condition (68-99% reduction).
