A microcomposite test procedure for evaluating the constituent properties of CMCs produced by chemical vapor infiltration is described. The analysis and experimental results demonstrate that the interface sliding resistance {tau}{sub o} can be obtained from the unload/reload hysteresis, after one (or more) matrix crack has been induced. The nonlinear strain can also be used to provide an independent determination of {tau}{sub o}, as well as give values for the misfit strain and the interface debond energy. Results obtained on SiC/C/SiC SiC/BN/SiC materials are evaluated.
