Abstract
The method of the analysis of a crack with bridging fibers in an infinite orthotropic elastic plate under remote uniform tensile stress is utilized to evaluate the mechanical properties of a hybrid composite with plual kinds of reinforcement fibers. Based on the evaluation of the tensile stress of the bridging fibers, the increment of the tensile stress loaded on the plate of the hybrid composite is confirmed by comparing the tensile stress calculated for the plate of composite reinforced by only one kind of fiber, which is the parent composite of the hybrid composite. The increment is affected by the interfacial shear strength of fiber and matrix, the length of crack and the number of bridging fibers.
