Abstract

Taking C/C composites of different structure and density as preform, C/SiC composites were prepared by reactive melt infiltration. The relationship among density, component content, thermal diffusion coefficient and friction properties of C/SiC composites was studied. Results show that the density of C/SiC composites increases with the decrease of carbon content; that the average coefficient of friction of short fiber C/SiC, low density needle punched C/SiC and high density needle punched C/SiC composites are 0.28, 0.28 and 0.42, respectively; that the friction stability increases with the increase of thermal diffusion coefficient; and that successive slippery friction surface is formed for short fiber C/SiC composites after friction test.
