Abstract
The fatigue life of unidirectional fiber reinforced SiC/SiC composites were predicted by a conventional method based on the Monte Carlo simulation assuming that fiber/matrix interfacial debonding was generates from single transverse-crack surface. The fatigue life predicted by this method was quite good agreement with the one obtained from fatigue tests. It was clarified that about twenty fibers were broken at the first loading and the catastrophic failure occurred in the material when the number of broken fibers reached to about one hundred. The variations in maximum strain ε_<max> were estimated using this method where the number of transverse-cracks was arbitrary applied. The tendency that the ε_<max> gradually increase with increase in number of cycles could be expressed qualitatively using this method. However, the calculated ε_<max> was fairly smaller than the experimental data, because the nucleation and development of the micro-cracks in the matrix and the variation in the angle of fiber direction under the fatigue process were not considered in this calculation.
