In this paper, the structural design and analysis of a fiber reinforced plastics (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, finite element method (FEM) analysis is employed to clarify the stress state in the vessel and to obtain a higher structural efficiency. Here, the liner and the FRP are both modeled with shell elements, and the offsets between them are modeled with rigid bar elements. Using the above methods, S-glass/epoxy FRP pressure vessels with aluminum alloy liners were manufactured experimentally. Autofrettage and single-cycle burst tests were conducted using hydraulic fluid pressurization. Good agreement between calculated and measured results was obtained.
