Abstract

The mechanical and tribological properties of carbon/silicon carbide (C/SiC) brake materials were compared with those of carbon/carbon (C/C) ones. The results show that the mechanical properties of C/SiC brake materials are higher than those of C/C, and C/SiC brake materials have overcome the disadvantages of C/C such as low static friction coefficient and insufficient stability of friction coefficient caused by humidity. Therefore, C/SiC is a new type of high performance brake materials. By analyzing the serving environmental characteristic of C/C aircraft braking materials, the optimizing design methods on the mechanical, thermo-physical properties, friction and wear properties, materials structure and manufacture process of C/SiC brake materials were discussed. It lays a foundation for realizing the co-design among materials' microstructure, mechanical properties, friction and wear properties.
