Preparation of Ceramic Fiber-Ceramic Matrix Composites by a Faster Chemical Vapor Infiltration Process

摘要

A new, faster process was developed for the fabrication of ceramic fiber-reinforced, ceramic-matrix composites by chemical vapor infiltration. Process and equipment improvements led to the fabrication of preforms with a higher fiber content, and infiltration improvements led to reduced infiltration run times and increased infiltrated densities. These improvements have produced composites with not only higher flexural strengths but also high strain values. The high strain values have been a goal of this work. 23 refs., 8 figs.
