Composite pressure vessels, used extensively for gas and fuel containment in space vehicles, are generally constructed with a metallic liner, the fiber reinforcement carrying the major portion of the pressure-induced load. The design is dominated by the liner's low strain at yield since the reinforcing fibers cannot operate at their potential load-bearing capability without resorting to pre-stressing (or autofrettaging). For pressure vessels with relatively large radius-to-wall thickness (R/t) ratios, pre-stressing may not be feasible. An ultra high-efficiency pressure vessel, which operates at the optimum strain capability of the fibers, can be potentially achieved with a "liner-less" construction. This paper reviews the design and manufacturing challenges to be overcome in the development of such a pressure vessel. These include: (1) gas/liquid containment and permeation, (2) defining the end fitting design in order to transfer the pressure load acting on it into the composite shell. (3) manufacturing processes.
