Carbon fabric (CF) was pretreated by air-plasma bombardment and then further modified by deposition of polydopamine on the surface of the pretreated CF. Epoxy resin composites reinforced by unmodified or surface-modified carbon fabric were fabricated. The friction and wear behaviors of the resulting composites were evaluated in a ring-on-block contact mode. The flexural strength and Rockwell hardness of the composites were also evaluated. The morphologies of the worn surfaces of the unmodified and modified composites were analyzed by scanning electron microscopy. The surface treatment increased the surface roughness and changed the surface topography of the CF, which contributed to enhancing the interfacial adhesion of the composites and thus improved the mechanical properties and tribo-performance. The friction and wear properties of both the unfilled and filled composites were highly dependent on the load and sliding velocity. Moreover, the results were supplemented with scanning electron micrographs to help understand the possible wear mechanisms.

碳纤维织物（CF）通过空气等离子轰击进行预处理，然后通过将聚多巴胺沉积在预处理过的CF表面上进行进一步修饰。制备了由未改性或经表面改性的碳纤维增强的环氧树脂复合材料。所得复合材料的摩擦和磨损行为以环对块接触模式评估。还评估了复合材料的弯曲强度和洛氏硬度。通过扫描电子显微镜分析未改性的和改性的复合材料的磨损表面的形态。表面处理增加了表面粗糙度并改变了CF的表面形貌，这有助于增强复合材料的界面粘合性，从而改善了机械性能和摩擦性能。未填充和填充的复合材料的摩擦和磨损性能都高度取决于载荷和滑动速度。此外，对结果进行了扫描电子显微照片的补充，以帮助了解可能的磨损机理。
