STUDIES ON FRICTION PROPERTY OF C/C COMPOSITES UNDER LOW ENERGY LOAD

摘要

C/C composites have been widely used as braking material and C/C composite braking discs have been equipped with many military and commercial aircraft in some advanced countries for years. The research and manufacture on C/C composite braking discs in China was just started at the middle of 1980's, According to the landing and initial braking factors of the aircraft, we studied the tribological property of C/C composites many times but fail of studying on relevant tribological properties under operating factors of low energy and low speed, such as taxing, this is not good for the aircraft designer and customers to have a fully understanding of the aircraft properties. Therefore, we here list a number of parameters, with it, we have satisfactorily done a series of experiments under low energy and low speed.
