The carbon fiber resin composite (CFRC) wound high-pressure vessel is the key equipment of high-pressure hydrogen storage technology. High pressure includes high energy in operation, so it is important to analyze the mechanics of this type of vessel. The constitutive performance of CFRC wound layer is anisotropic, and the layer arrangement is complexity, so it is difficult for mechanics analysis on a cylinder. Considering that the internal pressure in a cylinder is loaded by the aluminum alloy liner and the CFRC wound layers together, two models are built: The first model is the cylinder loaded by internal pressure in the hoop direction only. In this model, total hoop direction load is distributed into every layer under internal pressure. The second model is the cylinder loaded with the internal pressure on axial direction only. In this model, total axial load is distributed into all cylinders under internal pressure. Taking the boundary condition of continuous displacement between layers into account, a group of equations is built. From the equations, the solutions of the internal pressures in hoop direction and axial direction loaded by every layer can be obtained. After stresses are obtained, the optimal design can be done through this method. An example is given.
