To improve the oxidation resistance of carbon/carbon (C/C) composites at high temperature, the C/C composites were first slurry-coated by carbon, then pack cemented by mixtures of Si and graphite powder (60-80:10-25 wt/wt), followed by heat treatment to form C/C composites coated with a C/SiC layer, and finally a Si-Mo-Cr oxidation protective coating was prepared on the surface of the these composites...
Microwave assisted chemical vapor infiltration for the rapid fabrication of carbon/carbon (C/C) composites was investigated at 1 000–1 150 °C for different times using carbon felts as substrates and methane as carbon precursor. The temperature and density distribution in the felts were measured and the densification kinetics were investigated. It is found that the highest density of the C/C composite...
