Summary

3D-C/C-SiC model composites are used to study the influence of the addition of small amounts of SiC on friction properties of C/C composites. Samples are prepared by pressure-pulsed CVI (P-CVI) from toluene and MTS/H2 precursors. SiC is present in matrix as thin layers (1 to 15 layers, 100–170 nm thick, with 0.4 < VSiC < 6.2%) at different distances from fiber surface. Friction properties, as assessed from pin-on-disk (of same nature) experiments in controlled atmosphere at a given temperature, are presented. For VSiC < 3%, the addition of SiC does not change markedly the friction properties whatever the localization of a SiC single layer with respect to fiber surface. Conversely, for 3 < VSiC < 6%, the addition of SiC (as 3 to 15 layers) increases the coefficient of friction and the wear rate, both being linearly inter-related. The effect of SiC on the friction properties is tentatively discussed.
