in this paper, SiC coating on three-dimensional (3-D) braided carbon fiber was obtained, which was infiltrated with SiO2 sol into 3-D braided carbon fiber and then carbon-thermal reduced. The effect of carbon-thermal reduction process was examined. Thermal-oxidative stability of the 3-D braided carbon fiber coated with SiC was compared with original 3-D braided carbon fiber. The oxidation stability of the SiC coating/3-D braided carbon fiber was extended up to 900-1000 degreesC. After exposure to air at 900-1000 degreesC, the residual weight of the composite was 26-30%.
