A liquid or gaseous impervious barrier is disclosed for use in composite structures, such as pressure vessels or the like, which include a juncture at which a first filament wound laminate meets a second member, such as a second laminate or a fixed boss or fitting. The juncture is capable of separating upon flexing of the first and second laminates or members. The barrier includes a flexible member disposed between the first and second laminates at the juncture thereof, with the barrier member being sealed, as by bonding, to the first and second laminates to prevent moisture penetration about the barrier member. The barrier member is split from the exterior thereof partially therethrough to accommodate any separation at the juncture due to flexing of the first and second laminates. A folded film sheet is disposed in the split in the barrier member to prevent the split portions thereof from adhering to each other. A resilient member, such as an O-ring is disposed in the fold of the film sheet and fits into an enlarged portion formed at the base of the split in the barrier member, for holding the film sheet within the barrier member.
In a composite structure, such as a pressure vessel or the like, which includes a thickness of composite material terminating at a juncture with a fixed fitting or the like, and wherein said juncture is capable of separating under pressurization of said vessel, barrier means at said juncture comprising:
In a composite structure, such as a pressure vessel or the like, which includes a juncture at which a first laminate and a second laminate meet, and wherein said juncture is capable of separating upon flexing of said first and second laminates, barrier means at said juncture comprising:
In a composite structure, such as a pressure vessel or the like, which includes a circular juncture at which a first member and a second filament wound member meet, and wherein said circular juncture is capable of separating upon flexing of said first and second members, barrier means at said juncture comprising:
