Investigation of Oxide Fiber/oxide Matrix Composites With a Weak Interphase

Interface properties of four kinds of fiber model systems were obtained by analyzing pushout data with the linear model, the shear-lag model, and the Liang-Hutchinson model. These interface properties include interface fracture energy, coefficient of friction, clamping pressure, interface debond strength, and interface friction strength. A systematic study of the effect of interphase coating thickness on interface properties and pushout response was performed on two Al$\rm\sb2O\sb3$-matrix fiber model composites. The different pushout responses were distinguished by attributing them to the residual axial and radial stresses.
