Abstract
Tensile creep behavior of orthogonal 3D woven SiC fiber / SiC matrix composites has been investigated in detail. A new model for predicting the creep deformation behavior of SiC/SiC composites was proposed using shear-lag model, a linear visco-elastic model, and a empirical transverse crack growth model. Tensile creep tests were carried out at 1200 C in Ar atmosphere, and the experimental results were directly compared with the predicted values. The predicted results showed good agreement with the experimental results.
