碳纤维增强碳(CFRC)复合材料最初被引入航天器推进领域，由于其优异的摩擦学性能，很快开始应用于飞机刹车系统，取代传统的金属系统。每家公司都开发了自己的CFRC复合材料生产系统，每个制造商的信息都是唯一的，文献中很少有报道。在这项工作中，使用销盘式摩擦试验机对三种商用CFRC复合材料的摩擦学特性进行了研究。结果表明，石墨化指数在18~40%的粗糙或光滑层状结构的热解基复合材料对的平均COF在0.15~0.25之间，而由混合对、热解基与玻璃基或玻璃基对组装的对的平均COF在0.10~0.15之间。与热解复合材料相比，玻璃复合材料的磨损率可达到摩擦学对的9倍。
Carbon fiber reinforced carbon (CFRC) composites were initially introduced in spacecraft propulsion area and quickly started to be applied in aircraft braking systems, replacing conventional metallic systems, thanks to their excellent tribological properties. Each company develops their own CFRC composite production system, the information is unique to each manufacturer, and little is reported in the literature. In this work, tribological characterizations of three commercial CFRC composites are performed using a pin-on-disc tribometer. The results showed that the pairs assembled with pyrolytic matrix composites of rough or smooth laminar texture with graphitization index between 18 and 40% has an average COF between 0.15 and 0.25, while the pairs assembled with mixed pairs, pyrolytic matrix and glassy matrix, or pair of glassy matrix display average COF between 0.10 and 0.15. Wear which can reach a rate 9 times higher to the tribological pair of glassy composite when compared to a pyrolytic composite.
