Summary

This paper studies the high temperature creep behavior of short fiber-or whisker-reinforced-ceramic matrix composites. A unidirectional short fiber composite model under off-axis tension is first established by an advanced shear-lag approach and Eshelby's inclusion technique. The model is then extended to consider biased and random fiber orientations. Four-point bending creep experiments are performed on an SiC-whisker reinforced alumina composite at temperatures of 1150° and 1250°C in air. Finally, the analytical results are compared with experimental data for random whisker reinforced ceramics.
