5-dimension continuous silicon carbide fiber reinforced silicon carbide composites(SiC_f/SiC)on the interface with and without a pyrocarbon layer were fabricated by low pressure chemical vapor infiltration.

TaC was deposited by a chemical vapor infiltration(CVI) method with TaCl5-Ar-C3H6 system in the carbon fiber felt.

Chemical vapor infiltration processing (CVI) are considered as the most important technique for fabrication of carbon/carbon composites.

During thermal gradient chemical vapor infiltration(TCVI)fabricating C/C compos- ites,the complex change of the temperature field is difficult to solve by using analytics.

0% fabricated by the chemical vapor infiltration was studied using oxyacetylene ablation equipment.

5 D) carbon-fiber-reinforced silicon carbide(C/SiC) composite were prepared by the chemical vapor infiltration process and the tensile properties of the composites along the warp and weft direction were compared as a function of fiber architectures and processing-induced cracks.

Progress in Studies on Fabrication of C/C with CVI Techniques;

A novel highly efficient ICVI process, which is realized at ambient pressure by using propylene as feeding precursor gas and nitrogen as diluted gas, is developed to improve the tranditional ICVI processes.

The woven carbon fiber reinforced C-SiC binary matrix(C/C-SiC) composite manufactured by chemical vapor infiltration(CVI) method was investigated.
