Carbon-Ceramic Composites for Friction Applications

Carbon-based composites are known to possess excellent tribo properties coupled with high temperature stability. These requirements can be met using carbon-ceramic composites (CCC). CCC have been developed using different types of reinforcements in the form of particulate and fibers with phenolic resin as carbon matrix precursor. In particulate composites, calcined petroleum coke (CPC), fly ash, silicon carbide, and boron carbide were used as reinforcements, whereas in the category of fibrous composites, carbon fibers were used as an additional reinforcement. A comparison of fly ash-based carbon-ceramic composites (FACCC), carbon fiber-based carbon-ceramic composites (FCCC), and other particulate carbon-ceramic composites (OPCCC) has been studied.
