Abstract
Containers suitable for storing pressurized fluids at cryogenic temperatures of −62° C. (−80° F.) and colder are provided and comprise a self-supporting liner and load-bearing composite overwrap, whereby means are provided for substantially preventing failure of the container during temperature changes.

6. A container for storing a pressurized fluid comprising:
-
a self-supporting liner that provides a substantially impermeable barrier to a pressurized fluid; and composite material disposed adjacent to the self-supporting liner and having a coefficient of thermal expansion that is about the same as the coefficient of thermal expansion of the self-supporting liner at the interface with the self-supporting liner, and wherein the coefficient of thermal expansion gradually decreases as the distance from the interface increases in the composite material. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14)
