PROGRESS OF CERAMIC MATRIX COMPOSITES BRAKE MATERIALS FOR AIRCRAFT APPLICATION

Carbon fiber reinforced silicon carbide (C/SiC) brake materials are new highly competitive brake materials. They possess a series of outstanding advantages such as high strength, low density, good high temperature resistance, excellent friction properties, low wear rate and long life. Up to now, it has been equipped in some type of aircraft, and high end cars. The paper presents a brief state of the art of C/SiC brake materials. The attention is focused on manufacturing process, properties and wear mechanisms of C/SiC aircraft brake materials, as well as progress and future of the aircraft brake materials.
