Stress Concentratoin Due To Fibre-Matrix Fusion In Ceramic-Matrix Composites

Stress concentration in ceramic-matrix composites due to fibre-matrix fusion is investigated using finite-element modelling (FEM) in conjunction with experiment. FEM results indicate substantial stress concentration can be expected when the fibre and matrix are locally fused. The focus of the investiation is sealing through the formation of a reaction product layer. Direct sealing is also considered.
