Summary

A test system capable of long term mechanical testing at elevated temperatures was designed and developed. Room and elevated temperature quasi-static tensile and tension-tension cyclic fatigue tests were performed on 2-D woven SiCf(Nicalon*)/SiC matrix composites. Quasi-static tensile test results were found to be comparable with the available data in the literature. Operating at maximum cyclic load above the proportional limit load, the 23°C test results indicate a highly durable material whereas the 1000°C test resulted in a significantly shorter fatigue life.
