PRESSURE VESSEL LINER VENTING VIA NANOTEXTURED SURFACE

A pressure vessel (10') has a first end (14) with a first boss (16'), the first boss (16') having a first outer surface (38). The vessel (10') includes a liner (20') having a second outer surface (24), a shell (12) disposed over the second outer surface (24), and a first vent (22). The first vent (22) is formed onto at least a portion of the first outer surface (38) and at least a portion of the second outer surface (24). The first vent (22) includes a texture that provides a higher rate of gas flow through the first vent (22) than through a portion of an interface (26) of the liner (20') and shell (12) lacking the texture. In another aspect, a pressure vessel (10') has a first end (14a') and a second end (14b'), a plurality of first longitudinal vents (22) and a plurality of second longitudinal vents (22). At least one of first longitudinal vents (22) is circumferentially offset around the pressure vessel (10') from at least one of the second longitudinal vents (22). 20' Fig.4 16a' 2230 10' 14b' r - - -- - --- -- -- -- -- - -- 16b' Fig.5
