Abstract: A type IV conformable pressure vessel has improved mechanical coupling between an outer composite shell and a boss. The pressure vessel comprises an inner polymeric liner having a flare edge fixedly coupled to the boss. The boss has a bore in fluid communication with an interior of the pressure vessel. In addition, the boss has a shank extending between the liner and the outer composite shell. The shank includes a plurality of spikes projecting radially away from the boss. The outer composite shell of resin and fiber surrounds an outer periphery of the liner and an outer periphery of the shank. The spikes are embedded into the outer composite shell to mechanically fasten the outer composite shell to the boss.

Abstract: A pressure vessel and a method of manufacturing the pressure vessel is provided that reduces leaks in type IV pressure vessels having a liner with a corrugated section. The method includes providing a liner having a tubular portion having a corrugated section with circumferential corrugations providing alternating ridges and grooves arranged from one end to an opposing end of the corrugated section, applying a barrier to an outer surface of the corrugated section from one end to an opposing end of the corrugated section such that air voids are formed in annular cavities between the liner and the barrier; and applying resin to an outer surface of the barrier. The barrier prevents intrusion of the resin between the barrier and the liner in the corrugated section.

Abstract: A type IV pressure vessel has improved permeate gas management. The pressure vessel comprises an inner polymeric liner, a breather layer disposed on the liner, and an outer composite shell structure disposed on the breather layer. The breather layer is gas permeable, impermeable to liquids, and provides a flow passageway for gas permeating through the liner wall collected by the breather layer. The outer composite shell is formed by one or more layers of fiber of a first fiber type and resin. Gas permeating from an interior space of the liner is received by the breather layer and directed to a predetermined exit location on the pressure vessel.
