Preparation and Properties of Cf-Ti3SiC2-Cu-Graphite Composites

Abstract:

Copper-plated short carbon fiber/copper-plated Ti3SiC2-Cu-graphite composite, copper-plated short carbon fiber/Ti3SiC2-Cu-graphite composite with the same carbon fiber content and copper-plated Ti3SiC2-Cu-graphite composite were prepared by the powder metallurgy method. Physical and mechanical properties of these composites were tested. The dry friction tests of the composites under sliding velocity of 10m/s and load of 4.9N were conducted for 36 hours. The results show that the properties of the Cf-copper-plated Ti3SiC2-Cu-graphite composite such as electric conductivity, bending strength and wear resistance are remarkably increased than those of either Cf-Ti3SiC2-Cu-graphite or copper-plated Ti3SiC2-Cu-graphite composites.
