采用盘式摩擦磨损试验机研究了刹车压力和刹车速度对C/SiC航空刹车材料摩擦学性能的影响。制动温度随制动速度的增加而增加，受制动压力变化的影响较小。在相同的制动压力下，随着制动速度的增加，摩擦系数在10 m/s时达到最大值，然后下降。在相同的制动速度下，摩擦系数随制动压力的增大而减小。在相同的制动压力下，随着制动速度的增加，磨损率增大。制动速度低于20 m/s时磨损率较小，超过20 m/s后磨损率迅速增大。
Effects of braking pressure and braking speed on the tribological properties of C/SiC aircraft brake materials has been studied using a disk-on-disk type laboratory scale dynamometer. The braking temperature increased with increasing braking speed and was less affected by changes in braking pressure. The friction coefficient increased to the maximum value at 10m/s and then fell with the increase of braking speed at the same braking pressure. The friction coefficient decreased with the increase of braking pressure at the same braking speed. The wear rate increased with braking speed increasing at the same braking pressure. The wear rate was little at braking speed below 20m/s, and rapidly increased when the braking speed exceeded 20m/s.
