| 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,磨损率约为正常能载下的两倍.

| Abstract: | 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. |
