Abstract

A lightweight, high strength composite substantially all metallined pressure vessel is made by reinforcing the liner with an overwrap of resin impregnated filamentary material. End caps or polar boss fittings are attached to the vessel by means of a biasable seal. The pressure vessel is substantially free of failure forming stress concentrations and is substantially impermeable to the fluids stored therein. The vessel is capable of withstanding repeated pressurization-depressurization.

Claims

2. a boss having a flange portion mounted within the housing at the polar end opening adjacent a portion of the inner liner;

3. interface means secured to the boss and housing to provide a seal therebetween and to permit relative movement therebetween when the vessel is cyclicly pressurized and depressurized.

4. said seal permitting relative movement between the housing and the boss while maintaining the seal.

5. The vessel of claim 2 wherein said means comprises a rubbery polymer and an adhesive.

6. A pressure vessel capable of storing fluids under high pressure for extended periods of time and under repeated cyclic pressurizations and depressurizations comprising:

7. A pressure vessel comprising:

8. A pressure vessel comprising:

9. A high pressure vessel comprising;
