Summary

To address the need for strong and tough ceramic matrix composites for advanced structural applications, a study has been carried out to evaluate the role of fiber architecture for the structural toughening of ceramics. Specifically, 2-D fabrics (12 harness satin weave), with and without through-thickness stitching and 3-D braided Nicalon SiC reinforced Lithium Aluminum Silicate (LAS III) composites with a nominal fiber volume fraction of 40% were characterized in terms of their tensile, flexural, and through-thickness strength. In addition, the structural integrity and the damage resistance of these ceramic/glass matrix composites were examined by four point flexural fatigue, and three-point notch beam flexure test.
