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.
Claims27
A pressure vessel comprising:
- a liner having a cylindrical center portion and two domed portions;
- and
- a structural shell being disposed directly around the liner, and comprising:
- a first filament wound about the liner in a primarily hoop direction;
- and
- a second filament wound about the liner in a primarily helical direction;
- wherein the first filament and second filament are interwoven in a layer upon the liner, the layer comprises a three-dimensional interwoven construct, the layer is disposed directly around the cylindrical center portion and the two domed portions, and the layer comprises a continuous expanse from an outer surface of the cylindrical center portion of the liner to an outer surface of the pressure vessel without layer boundaries therebetween,
- the first filament and the second filament cross over each other at a first angle in a first portion of the three-dimensional interwoven construct, and the first filament and the second filament cross over each other at a second angle in a second portion of the three-dimensional interwoven construct, the first angle being about 90 degrees and the second angle being about 110 degrees.
A pressure vessel comprising:
- a liner having a cylindrical center portion and two domed portions;
- and
- a structural shell being disposed directly around the liner, the structural shell comprising:
- a reinforcement layer being disposed directly around the cylindrical center portion and the two domed portions of the liner, and comprising a first filament and a second filament interwoven upon the liner to form a three-dimensional interwoven construct, the first filament wound about the liner in a primarily hoop direction and the second filament wound about the liner in a primarily helical direction, and
- wherein the first filament and the second filament cross over each other at a first angle in a first portion of the three-dimensional interwoven construct, and the first filament and the second filament cross over each other at a second angle in a second portion of the three-dimensional interwoven construct, the first angle being about 90 degrees and the second angle being about 110 degrees, and
- wherein the first filament and the second filament are present in the reinforcement layer at the same proportions at various radial positions of the reinforcement layer from an outer surface of the liner to an outer surface of the pressure vessel.
