In this paper, the structural design and analysis of a FRP pressure vessel with a load-carrying metallic liner are presented. First, an outline design of the vessel is obtained utilizing netting analysis and membrane theory, and the shape of the dome is determined based on the concept of isotensoid. Then, FEM analysis is employed to clarify the stress state in the vessel and to obtain a higher structural efficiency. Here, the liner is modeled with shell elements and the FRP is modeled with offset shell elements. Using the above methods, S-glass FRP vessels with aluminum alloy liners are manufactured experimentally. Autofrettage and single-cycle burst tests are conducted using hydraulic fluid pressurization. Good agreement between calculated and measured results is obtained.
