The effects of the inner outer radius ratio on the through-thickness tensile stress and the in-plane tension stress are discussed with a focus on the curved beam based on an elastic foundation. The curved beam composed of two different materials was analyzed, and the location of the neutral axis for the in-plane tension stress was determined. Combining the boundary conditions of the zero internal and external surface stress, interlaminar normal stress, and continuous displacement in the thickness direction, the analytical solutions of the through-thickness tensile stress of the composite curved beam and in-plane normal stress were obtained under pure bending. Furthermore, the effects of volume fraction, material parameters and the placed position of the two kinds of materials on the stress of the composite curved beam were investigated. As a convenient and effective calculation strategy, the method could be extended to the application of curved beams with multiple layers of different materials for solving the strength of rectangular composite curved beams, especially the interlaminar strength in practical engineering.
