Ceramic composite components in a wide variety of shapes have been fabricated by a combination of chemical vapor infiltration (CVI) and chemical vapor deposition (CVD) of silicon carbide. Continuous Nextel and Nicalon ceramic fibers, which were woven into cloth, have been used as substrates for these depositions. Ceramic composite tubes and baskets as well as corrugated and flat panels have been fabricated by infiltrating and depositing approximately 0.08 cm of silicon carbide on the cloth substrates. By varying the weave architecture and regulating the deposition time, the porosity can be changed from open to vacuum tight.
