Summary

Hybrid Nicalon/Avco SCS-6 SiC yarns in a three-dimensional braid were fabricated and consolidated with LAS III. The resultant composite materials were characterized in terms of tensile, through thickness, and flexural properties. The effects of level of hybridization were examined and summarized. Photomicrographical evidence was used as verification of failure modes for the specimens. It was found that hybridization of these two fibrous materials presents a promising approach to the development of high temperature ceramic matrix composites with improved in-plane properties while maintaining damage tolerance associated with three dimensional fiber architectures.
