PRESSURE VESSEL SHEAR RESISTANT BOSS AND SHELL INTERFACE ELEMENT

摘要

A pressure vessel has a composite shell (18); a boss (16) defining a port (32) in the composite shell (18) and having a neck (28); and an interface element (34, 34A, 34B, 34C, 34D) disposed between the composite shell (18) and the boss (16). The interface element (34, 34A, 34B, 34C, 34D) is neither bonded to the composite shell (18) nor to the boss (16), thereby allowing for movement between the interface element (34, 34A, 34B, 34C, 34D) and the composite shell (18) and allowing for movement between the interface element (34, 34A, 34B, 34C, 34D) and the boss (16). The interface element (34, 34A, 34B, 34C, 34D) further includes a neck (38) disposed adjacent the neck (28) of the boss (16).
