A better understanding of the debond and pull-out processes is needed because they affect the fracture toughness of fiber reinforced composites. In this paper, a new stochastic model is proposed to predict the probability distributions of debond and pull-out lengths of fibers in unidirectional fiber reinforced composities. The stress distribution in a debonded fiber was determined under existence of friction between the fiber and matrix. By using this stress distribution and a weakest-link model, the probability distributions of debond and pull-out lengths were predicted. When the debond stress is assumed to be scatterd , the computational results predicted by the new stochastic model have good agreement with the experimental data by Beaumont et al.
