The carbon-carbon (carbon fiber reinforced carbon matrix) composites were applied in the finger seal and the tribological behaviors were investigated using UMT-2 tribology tester under the light loads condition. The friction coefficient and the wear rate were measured. Friction and wear mechanisms were analyzed using SEM (scanning electron microscope) method. Results show that the friction coefficient and wear rate are lower when the non-woven cloth is perpendicular to sliding surface. For the higher density material,with increasing load the wear rate increases with small amplitude and the friction coefficient decreases. The frequency has less effect on the wear rate compared to the load on wear rate,and the tribological behaviors are better with increasing frequency. SEM analysis indicates as follows. First,abrasive wear occurs under low frequency and low load. Second,increasing the frequency quickens formation of the wear debris into film,and self-lubricating effect is strengthened. Last,although wear debris are quickly squeezed into film with increasing load,severe wear occurs due to fibers exposure and fracture with the film further squeezed out and peeled off. The effect of load on wear is notable when the material density is lower. Selecting higher density material and the material with non-woven cloth perpendicular to sliding surface can effectively mitigate wear.
