Abstract

A method for producing silicon carbide whisker-reinforced ceramic matrix tubes by laminate processing is described. Laminate design methodology provides the opportunity to produce functionally graded microstructures. The process consists of tape-casting whisker-reinforced ceramic tapes, followed by tube winding, encapsulation, and hot isostatic pressing. Fully densified tubes with preferential whisker orientation due to the winding process are obtained. The strength of the tube material is comparable to that of similar whisker-reinforced, ceramic matrix laminate composites. The importance of slow pressurization during densification is explained.
