Summary

A variety of ceramic composite components 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, were the substrate. Both flat and corrugated panels as well as baskets and tubes have been made. By varying the weave architecture and regulating the deposition time, the porosity could be changed from open to vacuum-tight. Vacuum-tight seals were made by joining ceramic cloth by stitching and depositing silicon carbide. Flat ceramic composite panels, up to 0.8 ′ 0.8 m, have been fabricated. The composites' cross-sectional thickness ranged from 1 to 5 mm. Combustion test results with smaller composites at 1400°C for 800 hours have indicated a wide range in strength loss.
