The Application of Debond Length Measurements to Examine the Accuracy of Composite Interface Properties Derived From Fiber Pushout Testing

Finally, an experiment was designed and constructed to perform fiber pushout tests at temperatures up to 800$\sp\circ$C and in a controlled environment. Preliminary pushout tests on both a pristine and a transversely fatigued SiC/Ti-6-4 composite were conducted to assess the capabilities of this apparatus. A negligible force was required to slide the fibers in the fatigued samples at 400$\sp\circ$C, indicating that the fibers were debonded by the fatigue load. The identification of progressive debonding in metal matrix composites is also discussed.
