Abstract
The pressure vessel system can include a pressure vessel and an optional jacket. However, the system 100 can additionally or alternatively include any other suitable set of components. The pressure vessel can include a liner, an optional composite overwrap, and/or any other suitable components. For example, the pressure vessel can be a composite overwrapped pressure vessel (COPV) with a metallic liner (e.g., alloyed aluminum). The pressure vessel system can function to store fluid (e.g., cryo-compressed hydrogen) within an interior chamber.
Claims20
A system, comprising:
- a composite overwrapped pressure vessel (COPV), comprising:
- a liner comprising an alloy of:
- greater than 92.0% aluminum by mass, greater than 1.0% copper by mass, and greater than 0.2% manganese by mass;
- and
- a composite overwrap encapsulating the liner,
- wherein the COPV is configured to store cryo-compressed hydrogen at a cryo-compression temperature and pressure for hydrogen.

A system, comprising:
- a composite overwrapped pressure vessel (COPV), comprising:
- a liner formed from an alloy and configured to store cryo-compressed fluid at a pressure above 100 bar and a cryogenic temperature, the alloy comprising:
- greater than 92.0% aluminum by mass, greater than 1.0% copper by mass, and greater than 0.2% manganese by mass, wherein the alloy defines a fatigue crack growth rate exponent of less than 3.25 at 77 Kelvin within a linear elastic fatigue crack growth regime;
- and
- a composite overwrap surrounding the liner.
