Abstract
Official abstract text for this publication.
A composite pressure vessel assembly includes a plurality of lobes, each of the lobes having at least one interior wall and at least one curved wall, the plurality of lobes being positioned in a side by side arrangement and extending in a longitudinal direction from a first end to a second end. Also included is a plurality of end caps disposed at the ends of the lobes, wherein the plurality of lobes and end caps are formed of at least one fiber-reinforced polymer. A method of manufacturing a composite pressure vessel assembly is provided. The method includes forming a plurality of lobes consisting of at least one fiber-reinforced polymer. The method also includes forming a main body with the plurality of lobes, the lobes disposed in a side by side arrangement.
First claim
Opening claim text (preview).
What is claimed is: 1. A composite pressure vessel assembly comprising: at least three lobes, each of the lobes having at least one interior wall and at least one curved wall, the plurality of lobes being positioned in a side by side arrangement and extending in a longitudinal direction along respective centerlines and from a first end to a second end; and a plurality of end caps disposed at the ends of the at least three lobes; wherein the at least three lobes and end caps are formed of at least one fiber-reinforced polymer, the interior wall of one lobe is in contact with the interior wall of an adjacent lobe of the at least three lobes, the interior walls are angled, the centerlines are parallel to one-another and do not lie within a common plane, and the composite pressure vessel assembly is of an arcuate overall substantial geometry. 2. The pressure vessel assembly of claim 1 , wherein the at least three lobes are entirely formed of at least one fiber-reinforced polymer. 3. The pressure vessel assembly of claim 1 , wherein the at least three lobes and the plurality of end caps are formed as a single, integrally formed composite structure. 4. The pressure vessel assembly of any of claim 1 , wherein the at least one fiber-reinforced polymer comprises a fiber selected from the group comprising carbon, glass and aramid. 5. The pressure vessel assembly of any of claim 1 , wherein the at least one fiber-reinforced polymer comprises a polymer matrix comprising at least one of epoxy, vinyl ester, polyester, polyurethane, phenolic, polyamide or polyimide. 6. A composite pressure vessel assembly comprising: a plurality of lobes, each of the lobes having at least one interior wall and at least one curved wall, the plurality of lobes being positioned in a side by side arrangement and extending in a longitudinal direction from a first end to a second end; a first plurality of end caps disposed at the respective first ends of plurality of lobes; and a second plurality of end caps disposed at the respective second ends of the plurality of lobes, wherein the plurality of lobes and end caps are formed of at least one fiber-reinforced polymer, the first plurality of end caps are formed as one integral and unitary piece prior to attachment to the plurality of lobes, and the second plurality of end caps are formed as one integral and unitary piece prior to attachment to the plurality of lobes. 7. The composite pressure vessel assembly set forth in claim 6 , wherein the first and second plurality of end caps are attached to the respective first and second ends of the plurality of lobes by at a joint. 8. The composite pressure vessel assembly set forth in claim 7 , wherein the joint is a lap joint.
