 Title: The Application of Debond Length Measurements to Examine the Accuracy of Composite Interface Properties Derived From Fiber Pushout Testing Author(s): Bechel, Vernon Thomas Doctoral Committee Chair(s): Sottos, Nancy R. Department / Program: Theoretical and Applied Mechanics Discipline: Theoretical and Applied Mechanics Degree Granting Institution: University of Illinois at Urbana-Champaign Degree: Ph.D. Genre: Dissertation Subject(s): Engineering, Materials Science Abstract: 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.
