Abstract: Pressure vessels having a grooved liner and methods of forming the same are described. The pressure vessel includes a liner surrounding a cavity therein, an outer surface of the liner disposed opposite the cavity, a boss disposed at a first end of the liner, a composite layer surrounding the liner, an inner surface of the composite layer disposed proximate the liner, and a plurality of longitudinal grooves configured to release gas present between the inner surface of the composite layer and the outer surface of the liner. The liner defines a longitudinal axis therethrough. The boss and the outer surface of the liner define the plurality of longitudinal grooves therein. The plurality of longitudinal grooves extends along the longitudinal axis from the boss toward a second end of the liner. The composite layer spans each of the plurality of longitudinal grooves.
