The innovative technologies for space planes, space stations, high efficiency gas turbines, etc., are being developed for applications early in the next century. Research on inter-metallic compound matrix composites or carbon/carbon composites is essential for the development of light weight and heat-resistant structural materials. In the Institute, the synthesis process of a high purity titanium aluminide by the sputtering or CVD process and the interface bonding effect of synthesized silicon carbide-titanium aluminide composites are studied. (See upper figure.) The high temperature oxidation properties of titanium aluminide and high-performance carbon/carbon composites are evaluated. The methods for evaluating the performance in severe environments are also developed. (See lower figure.)
