摘要：

Oxide/oxide ceramic-matrix composites (CMC) are being demonstrated in engine components that are axisymmetric in shape, and subject to axisymmetric thermo-mechanical loadings. Traditionally, woven CMC materials used in these components are made from 0 degrees/90 degrees fiber architectures. In many cases, the highest stresses are not always coincident with the orientation of the reinforcing fibers. Tensile and creeps tests at 1100 degrees C on a +/- 45 degrees CMC composed of Nextel (TM) 720 fibers and a alumina-silica matrix (AS-0) have been performed. The +/- 45 degrees orientation has approximately two-thirds the ultimate tensile strength of the 0'/90' orientation. The creep rupture strength at 100 h for the +/- 45 degrees orientation is approximately one-third that of the 0 degrees/90 degrees orientation. Published by Elsevier Ltd.
