The Environmental Durability of Fiber Reinforced Ceramic Matrix Composites

Abstract

The main objective of this program is to investigate the environmental durability of ceramic matrix composites based on glass-ceramic and polymer pyrolysis matrices, with emphasis on the relationship between composite properties, microstructure, and chemistry, and the environment to which the composite is exposed. This environmental exposure will include the effect of oxidation, moisture, and corrosion, under conditions of high temperature and stresses. During the first year of the program, the composite system under study consisted of a barium-magnesium aluminosilicate (BMAS) glass-ceramic matrix reinforced with SiC/BN coated Nicalon SiC fibers. The results of these environmental durability tests on this composite system are discussed.
