  • Publication number: 20210041064
    Abstract: A method of manufacturing a high-pressure fluid vessel includes forming a first portion of a high-pressure fluid vessel with a molding process. The high-pressure fluid vessel includes a stack of capsules. Each capsule includes a first domed end, a second domed end, and a semicylindrical portion extending between and connecting the first domed end to the second domed end. The method further includes forming a second portion of a high-pressure fluid vessel with the molding process. The second portion of the high-pressure fluid vessel is positioned adjacent to the first portion of the high-pressure fluid vessel. The second portion of the high-pressure fluid vessel is welded to the first portion of the high-pressure fluid vessel.

  • Publication number: 20200353704
    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.

  • Patent number: 10647065
    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.
