Abstract
The application of slice compression tests to evaluate the interfacial properties of aligned ceramic matrix composites is addressed. A slice of the aligned composite, which is cut normal to the fiber, is subjected to a constant compressive stress and a constant compressive strain at the top and the bottom surfaces, respectively. The fiber protrusion length vs the applied stress relation during the loading-unloading cycle of the test is analyzed. The interfacial bonding, Coulomb friction at the debonded interface, Poisson's effect, and residual stresses are included in the analysis, and closed-form analytical solutions are obtained. Based on the analytical solutions, a methodology is established to extract the interfacial properties from experimental results. The roles of interfacial bonding, Poisson's effect, and residual stresses on the residual fiber protrusion after complete unloading are also addressed in the present study. ? 1993.
