High Performance, Thin Metal Lined, Composite Overwrapped Pressure Vessel
US Patent:
6401963, Jun 11, 2002
Filed:
Oct 16, 1998
Appl. No.:
09/173602

International Classification:
B65H 8100
US Classification:
220586, 220589, 220590
Abstract:
An innovative technology for composite overwrapped pressure vessels (COPVs) has been developed which significantly increases cost effectiveness, increases reliability, and reduces weight over state-of-the-art COPVs. This technology combines an innovative thin liner made of a metal having a high modulus of elasticity and a high ductility, a high-performance composite overwrap and a high-performance film adhesive at the overwrap/liner interface. The metal liner can be fabricated from readily available titanium alloy sheet and plate using a combination of spin forming and machining to fabricate components and electron-beam welding for tank assembly. The composite overwrap is filament-wound onto an adhesive-covered titanium liner and the overwrap and adhesive are co-cured in an oven to yield an integrated tank structure.
