Abstract: A method of manufacturing a composite vessel assembly (20) includes the steps of filling a first chamber defined by a first liner (28,30,32) with a first granulated material (96) through a first orifice (98) in the first liner. A vacuum is then applied to the first chamber, and the first orifice is plugged. The first liner may then be enveloped with a first layer (84) for structural rigidity followed by relief of the vacuum.

Abstract: A pressure vessel assembly includes a vessel including a wall defining a chamber and a circumferentially continuous lip projecting into the chamber from the wall. The lip defines a through-bore in fluid communication with the chamber. A nozzle assembly including a tube and a flange projecting radially outward from the tube. The tube includes a first portion projecting from the flange and through the through-bore and an opposite second portion projecting outward from the flange. The flange is in contact with the wall and the first portion includes an outer surface having a contour configured to produce sealing friction between the lip and the outer surface.

Abstract: A composite pressure vessel assembly includes a first vessel having a first inner layer and a second vessel having a second inner layer. An outer layer of the assembly is in contact with and substantially envelopes the first and second inner layers. A junction of the assembly has outer boundaries defined by segments of the first inner layer, the second inner layer and the outer layer. A cross-layered component of the assembly is disposed in the junction, the first and second inner layers and the outer layer for adding strength to the junction and restricting delamination.

Abstract: A method of making a composite article involves first forming an intermediate substrate. The intermediate substrate can be formed from fibers and an uncured thermoset polymer composition followed by partial cure, or from fibers and an uncured thermoset polymer composition followed by cure of the thermoset polymer composition and deposition of a thermoplastic on the surface of the substrate, or from fibers and an uncured thermoset polymer composition followed by cure and exposure of the substrate to organic solvent, a plasticizer, moisture, and/or heat. The intermediate substrate prepared according to any of the above techniques is then subjected to cold gas spray deposition to deposit a metal layer onto the intermediate substrate. In the case where the substrate was formed by partially curing a thermoset polymer composition, the metal-coated partially-cured thermoset polymer substrate is then fully cured.
