We investigate the fragmentation process in a single-fiber composite (SFC), using a cohesive zone model. The evolution of microscopic damage near a fiber break has been investigated in detail. The results indicate that cohesive parameters for the fiber-matrix interface control the microscopic damage near a fiber break and the fragmentation process. We discuss how the major damage mode near a fiber break transits from interfacial debonding to matrix cracking. The transition to a damage pattern dominated by matrix cracking makes it difficult to use the fragmentation process to evaluate interface properties in an SFC test. The discussion demonstrates that the fiber strength distribution can be obtained by fitting the fragmentation process while the estimation of interfacial properties based on SFC tests becomes difficult because of the damage transition to matrix cracking in the case of strong interface.
