Fiber Matrix Interface Effects in Failure of Ceramic Matrix Fiber Composites.

Abstract

Mechanical behavior of ceramic fiber composites has been investigated. Methods were developed for measuring mechanical properties of the fiber/matrix interface at individual fibers and micromechanics models were developed to analyze debonding and sliding at the interface. A fracture mechanics model for tensile failure of composites has been developed. Solutions from this model define several different failure mechanisms and provide relations between strength, toughness and conditions for transition in failure mechanism in terms of microstructural properties of the composite.
