Abstract: A plastic tank for a motor vehicle. The plastic tank includes a container wall composed of plastic, an opening arranged in the container wall, a removable cover member operable to close and open the opening, and a stiffening ring member, composed of an injection-moulded plastic, embedded into an edge of the container wall that surrounds the opening, the stiffening ring member being operable to directly or indirectly support the cover member when the opening is closed.

Abstract: A cryogenic tank comprising an inner container for holding a cryogenic medium, and an outer container surrounding the inner container to define a vacuum space. A pocket extends at least from the vacuum space into an interior space of the inner container. One or more functional components are arranged in the pocket. The one or more functional components include one or more heat exchangers, valves, control components and/or tubes.

Abstract: A method for producing a plastic tank includes preparing a tank wall as a hot extrudate. A reinforcing sheet is then attached to at least one region of the outer layer of the hot extrudate. After introducing the attached reinforcing sheet and the hot extrudate into a shaping tool, the shaping tool performs shaping of the hot extrudate and the attached reinforcing sheet to form the tank wall, while simultaneously enhancing the attachment of the reinforcing sheet to the tank wall.

Abstract: A method of producing a plastic tank includes preparing a tank wall as a hot semi-finished sheet, in which at least one outer layer of the hot semi-finished sheet is composed of a first material. A reinforcing sheet, composed at least partially of the first material, is then attached to at least one region of the outer layer of the hot semi-finished sheet via a weld connection. The hot semi-finished sheet with the attached reinforcing sheet is then shaped to form the tank wall while simultaneously enhancing the attachment of the reinforcing sheet to the tank wall.

Abstract: A plastic tank for a motor vehicle and a method for producing such a plastic tank for a motor vehicle. The tank shell has a multi-layered structure, including at least one layer composed of high-density polyethylene, at least one barrier layer, and at least one regrind layer composed of recycled plastic arranged between the at least one layer composed of high-density polyethylene and the at least one barrier layer. The at least one regrind layer and/or the at least one layer composed of high-density polyethylene contains spherical fillers or fibrous fillers.
