A Comprehensive Study on Microstructure Mechanics Relationships of Ceramic Matrix Composites

Abstract

The background of this research stems from the need to understand the physical mechanisms of brittle matrix cracks in fiber reinforced ceramic matrix composites. Three major tasks are performed during the research: an in-house fabrication facility is established; a testing technique is developed; and a theory for matrix crack initiation and a numerical simulation method is formulated. A preliminary correlation between theory and experiment is accomplished. This report contains two individual technical papers; one describes the details of the experimental aspects and the other describes the theoretical and the simulative aspects. Ceramic matrix composites, Matrix cracking stress, Specimen fabrication, Testing, Theory, Simulations, Uniaxial fiber, Fracture mechanics, Oxidation, Fiber breaks.
