Abstract

Oxide fibre-reinforced / oxide matrix ceramic composites have the potential of existing high-temperature degradation in the increasingly aggressive environments of emerging applications for this still-evolving class of materials. An alumina (NextelTM) fibre-reinforced / alumina matrix composite with an oxidation-resistant boron nitride/silicon carbide interphase was investigated for its high temperature performance. Room-temperature tensile tests of specimens which had been exposed to 600, 800, 1000 and 1200 °C temperatures in ambient air for 10 and 100 h revealed time- and temperature-dependent retained strength behaviour. The effects of residual stress state and degradation of the interphase material on resulting mechanical performance were evaluated using load-unload tensile tests. Impulse resonance tests for elastic modulus at temperature, thermogravimetric/differential thermal analyses and post-test fractography were used to substantiate the micro mechanics of the observed tensile behavior.
