The influence of fiber/matrix interfacial properties on both the initial fiber/matrix debonded length and the stress associated with a bridging fiber at elevated temperatures was studied, including the process-induced residual stress, surface roughness and shear strength. The fiber bridging process was simulated using finite element method applied to concentric three-phase cylinders representing the fiber, interphase and matrix phases. Three temperatures applied to the fibers were also investigated. Both the initial debonded length and the bridging fiber traction range increased with increasing temperature and with decreasing coefficient of friction.
