Fatigue Behavior of a Cross-Ply Ceramic Matrix Composite Under Strain Controlled Tension-Tension and Tension-Compression Loading

Abstract

The purpose of this study was to investigate the fatigue response of a cross-ply (0/90)es Nicalon/Calcium-Aluminosilicate (Nicalon/CAS) ceramic matrix composite at room temperature under strain controlled tension-tension and tension-compression fatigue loading. The primary objectives were to determine strain fatigue limits (fatigue life of at least 1,000,000 cycles) for both loading cases and to complete a fatigue life diagram (i.e. strain range versus fatigue life, delta epsilon for all tests. Failure mechanisms were also studied. The average initial modulus value for this lay-up was 120 GPa.
