1. For use in fabricating a pressure vessel, a method of forming a dis-bond membrane between a structural outer wall and an inner liner having a cylindrical section and dome ends, comprising: installing a cylinder section of a barrier film around the cylindrical section of the liner, wherein the bar
1. For use in fabricating a pressure vessel, a method of forming a dis-bond membrane between a structural outer wall and an inner liner having a cylindrical section and dome ends, comprising: installing a cylinder section of a barrier film around the cylindrical section of the liner, wherein the barrier film is a thermoplastic having a softening temperature greater than a cure temperature of the structural outer wall, and wherein the inner liner has a softening temperature that is less than a cure temperature of the structural outer wall; andinstalling dome sections of the barrier film over the domed ends of the liner, including stretching the dome sections of the barrier film to conform to the dome ends and overlap a portion of the cylinder section of the barrier film. 2. The method of claim 1, wherein installing the cylinder section of the barrier film includes attaching the cylinder section of the barrier film to the cylindrical section of the liner. 3. The method of claim 2, wherein attaching the cylinder section of the barrier film is performed using an adhesive tape. 4. The method of claim 1, wherein installing the dome sections of the barrier film includes: applying an adhesive along outer edges of the cylinder section of the barrier film, andadhering the dome sections of the barrier film to the adhesive. 5. The method of claim 4, wherein: applying the adhesive along the outer edges of the cylinder section of the barrier film is performed by applying an adhesive tape to the outer edges of the barrier film, andadhering the dome sections of the barrier film to the adhesive includes tacking outer edges of the dome sections of the barrier film to the adhesive tape. 6. The method of claim 4, wherein installing the dome sections of the barrier film includes removing a part of the outer edges of the cylinder section of the barrier film extending beyond the adhesive. 7. A method of fabricating a pressure vessel having a constant cylindrical body and dome-shaped outer ends, comprising: fabricating a thermoplastic liner having a cylindrical section and dome ends;installing a cylinder section of a barrier film on the thermoplastic liner;stretching dome sections of the barrier film respectively over the dome ends of the thermoplastic liner;attaching the dome sections of the barrier film to the cylinder section of the barrier film; andfabricating a composite structural outer wall over the thermoplastic liner, wherein:the thermoplastic liner has a softening temperature that is less than a cure temperature of the structural outer wall, andthe barrier film is a thermoplastic having a softening temperature that is greater than the cure temperature of the structural outer wall. 8. The method of claim 7, wherein stretching the dome sections of the barrier film include drawing the dome sections of the barrier film into overlapping relationship to the cylinder section of the barrier film. 9. The method of claim 7, wherein attaching the dome sections of the barrier film to the cylinder section of the barrier film includes: applying double-sided adhesive tape on edges of the cylinder section of the barrier film, andadhering edges of the dome sections of the barrier film to the double-sided adhesive tape. 10. The method of claim 9, further comprising: trimming away an edge of the cylinder section of the barrier film extending beyond the double-sided adhesive tape. 11. The method of claim 9, wherein: attaching the dome sections of the barrier film to the cylinder section of the barrier film includes applying Mylar® film along outer edges of the cylinder section of the barrier film, andapplying the double-sided adhesive tape is performed by applying the double-sided adhesive tape on the Mylar® film. 12. The method of claim 7, wherein: the structural outer wall includes a thermoset resin. 13. The method of claim 7, further comprising: curing the structural outer wall, and using the barrier film to prevent bonding of the thermoplastic liner and the structural outer wall. 14. The method of claim 7, wherein fabricating the structural outer wall includes: fabricating composite dome caps,installing the composite dome caps respectively on the dome ends of the thermoplastic liner, andwrapping composite material around the cylindrical section of the thermoplastic liner. 15. A dis-bond membrane between thermoplastic liner having cylindrical section and dome ends, and a fiber reinforced thermoset outer wall surrounding the liner, comprising: a barrier film between the outer wall and the liner, the barrier film including a cylinder section, and dome sections respectively attached to and overlapping opposite ends of the cylinder section, wherein each of the dome sections of the barrier film is stretched over the dome ends of the liner, wherein:the liner has a softening temperature that is less than a cure temperature of the thermoset, andthe barrier film is a thermoplastic having a softening temperature greater than the cure temperature of the thermoset. 16. The dis-bond membrane of claim 15, wherein: the liner is formed from polyethylene, andthe barrier film is formed from fluorinated ethylene propylene. 17. The dis-bond membrane of claim 15, wherein: the softening temperature of the liner is approximately between 250° F. and 275° F., andthe cure temperature of the thermoset is approximately between 250° F. and 300° F. 18. The dis-bond membrane of claim 15, wherein: the dome sections of the barrier film have edges adhesively attached to the cylinder section of the barrier film. 19. The dis-bond membrane of claim 15, wherein the barrier film is one of: polyester, andpolyether ether ketone.
