碳/碳复合材料具有密度小、耐高温、耐磨损、抗腐蚀、良好的化学稳定性和较低的热膨胀系数等优点,被广泛应用于飞机刹车系统中。本文介绍了飞机碳刹车盘的结构和工作原理,分析了碳/碳复合材料在飞机刹车盘上应用的优缺点,并提出了飞机刹车盘的维护方法。 Carbon / carbon composites have the advantages of low density, high temperature resistance, wear resistance, corrosion resistance, good chemical stability and low coefficient of thermal expansion. They are widely used in aircraft braking systems. This paper introduces the structure and working principle of the aircraft carbon brake disc, analyzes the advantages and disadvantages of the carbon / carbon composite used in the aircraft brake disc, and proposes the maintenance method of the aircraft brake disc.
