A carbon-fibre-reinforced silicon carbide composite was prepared by chemical vapour infiltration. A SiC and SiC/Si-Zr coating were deposited on the composite to investigate the effect of different coatings on the oxidation behaviour of 3D-C/SiC composites. The composite decreased in weight below 1000 deg C and increased in weight above 1000 deg C. With an increasing oxidation time, the weight loss increased greatly and the weight gain increased little.
