Abstract
A pressure vessel is provided that has a structural shell formed by winding filaments upon a substantially cylindrical form. The structural shell has a first filament and a second filament. The first filament includes of a first material. The first filament is wound about the form in a primarily hoop direction. The second filament includes a second material. The second material is different from the first material. The second filament is wound about the form in a primarily helical direction. The first filament and second filament are interwoven in a layer upon the form.

1-27. (canceled)
A pressure vessel comprising:
- a liner having a cylindrical center portion and two domed portions and extending along a longitudinal axis;
- and
- a structural shell being disposed directly around the liner, and comprising:
- a first filament wound about the liner at a first angle relative to the longitudinal axis;
- and
- a second filament wound about the liner at a second angle relative to the longitudinal axis;
- wherein the first filament and second filament are interwoven from an outer surface of the cylindrical center portion of the liner to an outer surface of the pressure vessel directly around the cylindrical center portion and the two domed portions, and
- wherein neither the first angle nor the second angle is parallel to the longitudinal axis.
A pressure vessel comprising:
- a liner having a cylindrical center portion and two domed portions and extending along a longitudinal axis;
- and
- a structural shell being disposed directly around the liner, and comprising:
- a first filament applied onto the liner as a single strip at a first angle relative to the longitudinal axis;
- and
- a second filament applied onto the liner as a single strip at a second angle relative to the longitudinal axis;
- wherein the first filament and second filament are interwoven from an outer surface of the cylindrical center portion of the liner to an outer surface of the pressure vessel directly around the cylindrical center portion and the two domed portions.
A method comprising:
- mounting a form to a spindle;
- rotating the form about a longitudinal axis of the form using the spindle;
- while rotating the form, winding a first filament onto the form at a first angle relative to the longitudinal axis;
- while winding the first filament, simultaneously winding a second filament onto the form at a second angle relative to the longitudinal axis;
- wherein simultaneously winding of the first filament and the second filament directly onto the form to cover an exterior surface of the form provides an interwoven structure disposed about and reinforcing the form, and
- wherein neither the first angle nor the second angle is parallel to the longitudinal axis.
