On the basis of an elasto-plastic analytical solution for laminating structure, making use of automatic dynamic increment nonlinear finite element analysis software ADINA [1], the self-strengthening research of a FRP (fiber reinforced pressure) vessel with metallic liner is presented in this paper. A self-strengthening pressure is determined to make the aluminum inner layer elastic deformation under hydrostatic pressure and to obtain the best ratio of the vessel’s volume and weight. Thus, the gas-tightness and fatigue strength of FRP vessel were improved. In addition, the influence of thermal load on the vessel was also calculated.
