In this paper, a method for calculating the stability of a sandwiched composite beam was proposed.The transfer matrix method was applied to address the stability of the marine composite joint structure.The equivalent bending stiffness and equivalent shear stiffness of the marine sandwiched composite beam were derived as part of the stability analysis method.The results were compared with the numerical simulation and the stability test results to verify the calculation method.The result shows that the proposed method has a high stability solution precision for the marine composite joint structure.The research in this paper enriches stability calculation methods of composite joint structure and provides a reference for the engineering design and manufacture of composite joint structure.
