Abstract: By comparing and analyzing the characteristics and friction properties of the compounds materials, the powder metallurgy materials, carbon/carbon and C/C-SiC composites, it is concluded that C/C-SiC composites is a high property ceramic friction materials which can meet the requirement of high speed and high energy braking. The main advantages and shortage of liquid polymer infiltration method, chemical vapor infiltration method, and reactive melt infiltration method for fabricating C/C-SiC braking materials are summarized, and reactive melt infiltration method is a promising industrialization technology. The microstructure, mechanical properties, friction and wear properties, and application of C/C-SiC composites made in China are introduced. The property characteristic of C/C-SiC ceramic braking materials are reviewed.
