Summary

A method was devised for evaluating the high temperature stability of two types of Nicalon™ SiC fiber. It is based on monitoring the physical, chemical, and structural developments in fibers heat treated in oxidizing and nonoxidizing environments at 1000°, 1200°, and 1400°C. The results obtained indicate that ceramic grade Nicalon™ demonstrated improvements in degradation resistance and strength retention over its predecessor, standard grade fiber. Experimental observations were explained by differences between microstructures which had resulted for the two fiber types under the same test conditions.
