Abstract

The paper considers the process of friction of carbon-carbon-fiber composite materials (C/C-fiber composite) and investigates the formation of a film of wear products (third body) on the friction surface. The friction and wear tests of the composites are carried out in the temperature and pressure range typical for the operation of aircraft-braking systems and other highly loaded friction units. The friction surface of the material and the third body are investigated by scanning electron microscopy, scanning probe microscopy, and Raman spectroscopy. The influence of the presence of a third-body film and its thickness on the coefficient of friction and the intensity of material wear are estimated.

表面膜（第三体）对碳纤维复合材料摩擦磨损过程的影响

摘要

本文考虑了碳-碳-纤维复合材料（C/C-纤维复合材料）的摩擦过程，研究了摩擦表面磨损产物（第三体）膜的形成。复合材料的摩擦和磨损测试是在飞机制动系统和其他高负载摩擦装置运行的典型温度和压力范围内进行的。通过扫描电子显微镜、扫描探针显微镜和拉曼光谱研究了材料和第三体的摩擦表面。估计了第三体膜的存在及其厚度对摩擦系数和材料磨损强度的影响。
