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.
