Friction and Wear Properties of Solid Lubricants Filled/Carbon Fabric Reinforced Phenolic Composites

The carbon fabric composites (CFC) filled with the particulates of graphite, MoS2, and PTFE, respectively, were prepared by dip coating and hot press molding technique. The tribological properties of the resulting composites were investigated systematically on a model ring-on-block test rig under dry sliding conditions. Experimental results showed that the addition of graphite and MoS2 significantly improved the friction and wear behavior, but PTFE as filler was harmful to the improvement of the tribological properties of the CFC. Tribological tests also revealed that the CFC showed better tribological properties under higher load and exhibited worse tribological properties under higher sliding speed. Moreover, it also can be concluded that the transfer film formed on the counterpart surface during the friction process largely accounted for the friction and wear behavior of CFC.
