Abstract:To improve the friction coefficient stability of resin-based friction material, and improve the property
of inhibit thermal degradation. Carbon fibers as reinforcing fibers, carbon fibers reinforced resin based friction materi
als were prepared by thermoforming process. Friction and wear properties were measured through XD-MSM type con
stantspeed friction tester, the effects of different carbon fiber content on friction and wear properties of resin -based
friction material were studied. Worn surface morphology was observed by using VK-X200 three-dimensional laser scan
ning microscope, and wear mechanism was discussed. The results show that the hardness, compressive strength and
shear strength of carbon fibers reinforced resin-based friction materials were improved, and increased gradually with
the increase of carbon fiber content. Carbon fiber improved the friction coefficient stability of resin-based friction mate
rial, enhanced the wear resistance and changed the form of friction and wear. The properties of friction coefficient sta
bility and inhibit thermal degradation was great, and the wear mechanism was fatigue wear when the mass percentage
of carbon fiber was 4wt% in the resin-based friction material.
