“…Carbon fiber/carbon-silicon carbide (C f /C-SiC) composites composed of carbon fibers, carbon matrix and silicon carbide matrix is now being widely applied in high-performance brake system for supercars, racing cars, crane, elevators, and aircraft, etc., due to their advantages like light weight, high specific strength/specific mode, high temperature resistance, high fatigue resistance, excellent friction and wear performance. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15] Due to the high manufacture cost of C f /C-SiC composites, the application of full ceramic braking system in the field of heavy-duty is limited. Currently, C f /C-SiC composites coupled with metal counterpart seems to be a favorable solution to give full play to the advantages of the heat resistance and wear resistance of C f /C-SiC composites.…”

Ternary Cu-Fe-Si alloy were applied to modify tribological behavior of carbon fiber/carbon-silicon carbide (C f /C-SiC) composites by reactive melt infiltration.Microstructures, physical properties and tribological properties on a full-scale train brake test rig of the modified composites were studied. Results indicate that both Cu and Fe-Si alloy as matrices lead to significantly enhanced thermal conductivity and compressive strength for C f /C-SiC composites. Moreover, the average friction coefficient of the modified composites is between 0.25 and 0.55, which is higher than that of copper metal matrix composites. In addition, the average volume wear rate of the modified composites is only 0.168 cm 3 /MJ. The C f /C-SiC composites modified by Cu and Fe-Si alloy with improved physical properties and tribological properties meet the technical requirement and show high application potential in express train brake systems.
