A linerless tank structure has a body that defines an enclosed interior volume. The body has a cylindrical section having an axis of symmetry and a dome section coupled with the cylindrical section. The construction of the pressure vessel includes multiple fiber plies. At least one of the fiber plies is a helical ply having fibers traversing the dome helically about the axis of symmetry. At least a second of the fiber plies is a braided or woven ply.

What is claimed is: 1. An all-composite pressure vessel or storage tank defining an enclosed interior volume and comprising:a plurality of structural plies;one or more barrier plies comprising:reinforcement fibers that impart a predictable, burst-strain capacity to the barrier plies; anda polymeric resin that provides a resistance to microcracking and incipient leakage under pressurization and leading up to strains that exceed the burst-strain capacity of the barrier plies;wherein the barrier plies exhibit a burst strain that is less than a burst strain exhibited by the plurality of structural plies.
