Patent number: 11506335Abstract: A plastic tank liner for the storage of a pressurized fluid includes: two ends; two elongated cylindrical sections, the two cylindrical sections having different diameters; and one connecting section connecting the two cylindrical sections. The connecting section has a concave portion connected to the cylindrical section of smaller diameter, and a convex portion adjacent to the cylindrical section of larger diameter. The convex portion has an isotensoid shape. Two convex domes are located on both ends of the plastic tank liner so that each of the domes is connected to a different cylindrical section.Type: GrantFiled: June 26, 2019Date of Patent: November 22, 2022Assignee: PLASTIC OMNIUM NEW ENERGIES FRANCEInventors: Axel Seifert, Geert Nouwen

Patent number: 11435033Abstract: A composite pressure vessel includes: a body including an inner liner which includes a cylindrical portion extending along a longitudinal axis, and which is made of a thermoplastic polymer material; and an outer thermoset reinforcing structure wrapped around the body and made of a continuous fiber reinforced thermoset matrix composite, including reinforcing fibers and a thermoset matrix. The body further includes a thermoplastic reinforcement layer made of a continuous fiber reinforced thermoplastic composite, including reinforcing fiber and a thermoplastic matrix, which is adhered to the cylindrical portion of the inner liner.Type: GrantFiled: June 26, 2019Date of Patent: September 6, 2022Assignee: Plastic Omnium New EnergiesInventors: Geert Nouwen, Philippe Willems, Axel Seifert

Patent number: 11299312Abstract: The present invention describes a method for producing a leak-tight vessel for holding a gas and/or liquid, comprising the steps of winding a heat-sealable thermoplastic barrier strip around a removable mandrel in such a way that each strip fragment overlaps with a substantially parallel strip fragment over at least a lateral overlapping distance, consolidating the overlapping strip fragments so as to form a gas and/or liquid tight layer, winding a fibrous material around the gas and/or liquid tight layer, thereby leaving an opening large enough for removing the mandrel. The invention also describes a leak-tight vessel produced in this way.Type: GrantFiled: May 10, 2019Date of Patent: April 12, 2022Assignee: Covess N.V.Inventors: Tony Vanswijgenhoven, Dieter Vanswijgenhoven, Axel Seifert

Patent number: 11015762Abstract: A pressure vessel for storing a fluid at high pressure includes: a liner and a composite laminate shell coupled to an outer surface of the liner. The liner has an inner surface delineating an inner wall of a cavity and the cavity includes a dome-shaped region having a central opening. An access channel is traversing the composite laminate shell for providing an access to the cavity. The central opening is facing an entrance of the access channel. A boss connector, located or partly located within the access channel, includes an inner bore part configured for receiving a valve or a plug, and an outer neck part including a plurality of interspaced rib elements protruding into the composite laminate shell for optimizing a pressure distribution in the laminate shell.Type: GrantFiled: June 26, 2019Date of Patent: May 25, 2021Assignee: PLASTIC OMNIUM ADVANCED INNOVATION AND RESEARCHInventors: Els Mahieu, Geert Nouwen, Philippe Willems, Axel Seifert
