摘　　要：研究了碳／碳（简称Ｃ／Ｃ）复合飞机刹车材料在低能载条件下的摩擦磨损性能，分析了刹车力矩与刹车速度之间关系曲线，探讨了Ｃ／Ｃ复合材料因能载变化出现摩擦系数最大值的根本原因。结果表明：随着刹车比压增加，摩擦系数最大值下降；低能条件下Ｃ／Ｃ复合材料摩擦面较粗糙。The low energy friction and wear properties of carbon/carbon (C/C) composites used for aircraft brakes were studied, curves of relationship between the moment of brake force and brake velocity were analyzed, and the essential cause was discussed of why C/C composites possess a maximum friction coefficient when energy is changed. The results show that the maximum friction coefficient is decreased as the specific pressure is increased. The friction surface of C/C composites is rougher in low energy condition. The wear rate is about twice as large as in normal energy conditions.
