Abstract:
The purpose of this study was to investigate the fatigue response of a cross-ply 090es NicalonCalcium-Aluminosilicate NicalonCAS 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.
