Description

Ceramic composites are intended to take advantage of the high temperature capabilities of ceramics while minimizing the disadvantages caused by their very brittle nature. The particular material under study consists of a Nicalona fiber weave reinforcing fabric in a silicon carbide matrix formed by a chemical infiltration process [1]. The process can result in high porosity (10–50%) and voids because of incomplete infiltration by the SiC-containing vapor. The basic objective of this NDE study is detection and characterization of the porosity and voids.
