Abstract

An improved shear-lag model considering the interface roughness effect is established in this paper to analyze the carbon fiber pullout behavior from a thermosetting epoxy resin matrix. Using the new model, we predict the effect of interface roughness on the applied load-displacement relations, the interfacial shear strength and fracture toughness of composites. The theoretical results agree well with the experimental data, which should be helpful for the optimal design of interfaces in carbon-fiber reinforced epoxy composites.
