A tank that includes a tank wall composed of a plastic material, and at least one reinforcing profile member configured to minimize deformation of the plastic tank. The at least one reinforcing profile member is configured for arrangement on an outer side of the tank wall to be engaged by the tank wall and establish a positive material bond connection therewith. The at least one reinforcing profile member has a retaining geometry region with a plurality of openings through and/or into which material of the tank wall extends and onto a rear side of the reinforcing profile member facing away from the tank wall to thereby establish the positive material bond connection between the tank wall and the at least one reinforcing profile member at the retaining geometry region.

A multi-lobe seal for a sealing device for sealing an opening in a multi-layer wall of a fuel tank, the multi-layer wall having a layer of fuel barrier material and an opening in the multi-layer wall, the multi-lobe seal being fuel-impermeable and capable of being positioned in contact, at the opening in the multi-layer wall of the fuel tank, between the layer of fuel barrier material of the multi-layer wall of the fuel tank and a component, is disclosed. The multi-lobe seal includes, on the face capable of being in contact with the layer of fuel barrier material of the multi-layer wall, at least two protrusions, one of which leans on the layer of fuel barrier material of the multi-layer wall.

A composite fuel tank includes a tank-shell and a tank-liner, located within the tank-shell. The tank-shell is formed from a composite layup that is placed, consolidated, and cured on a bladder. The bladder forms the tank-liner after formation of the tank-shell.

A high-pressure tank includes a liner for storing a fluid, and a reinforcing layer covering an outer surface of the liner and including a fiber wound around the liner and a resin. The reinforcing layer includes a helical layer group including laminated helical layers, and a large-angle layer provided adjacent to the helical layer group and on the liner-side. The helical layer group includes an innermost layer that is closest to the liner and that is one of first and second helical layers respectively having the largest and second largest fiber winding angles, an outermost layer that is closest to an outer surface of the high-pressure tank and that is the other one of the first and second helical layers, and an intermediate layer disposed between the innermost and outermost layers and including a helical layer that is smaller in winding angle than the innermost and outermost layers.

A method of forming a self-sealing fuel tank includes: providing a container including internal surfaces and external surfaces and configured to hold a fuel; forming a latex coating layer over at least a portion of the internal surfaces and/or external surfaces; depositing or encapsulating an environmental layer over at least a portion of the latex coating layer; where the latex coating layer swells when contacted with the fuel; and where the latex coating layer is formed from a latex coating composition that is substantially free of a non-ionic associative thickener.

A system and method for manufacture of the system are provided. In one example, the system comprises a first component, a second component securing the first component to a portion of the system, and a flexible strip with an abrasion resistant coating including a copolymer. The first component or the second component includes a corrosion coating on an exterior surface and the flexible strip is interposed between a surface of the first or second component and the corrosion coating.

A tank made of resin provided with a barrier layer, which prevents the barrier layer from rolling up and has improved durability. In a tank made of resin that includes a barrier layer provided on an inner surface of a tank body made of resin, an opening part is provided in the barrier layer, a thick part projecting toward an inside or an outside of the tank body is provided in a resin layer at an outer peripheral part of the opening part, and the barrier layer and a casting flange part at a base of an oil filling port tubular part are molded with the resin of the tank body in a state in which the casting flange part is located at the thick part.

A compartment for storing fuel in a vehicle having a protective outer structure and an inner structure. The protective outer structure is maintained in position relative to the vehicle during normal operation of the vehicle. The inner structure, which holds fuel, is positioned in the outer structure. The inner structure is maintained in position relative to the outer structure and relative to the vehicle during normal operation of the vehicle. During an impact to the vehicle, the inner structure is configured to move independent of the outer structure.

A method of manufacturing a high-pressure tank includes: forming a vessel body including a body portion having a cylindrical shape, a domical portion having a hemispherical shape and provided at an end of the body portion, and a neck portion extending from the domical portion in an axial direction of the domical portion; winding fibers around an outer peripheral surface of the vessel body to form a plurality of fiber layers laminated in a radial direction of the vessel body; and placing, in a mold, the vessel body around which the fibers have been wound, and then injecting a resin onto the neck portion in an axial direction of the vessel body to impregnate the fibers with the resin.

A tank mounting structure includes a frame, a band, and a tank protector. The frame is configured to fix the tank. The band is configured to fix the tank in a state where the band sandwiches the tank with the frame and the band deforms in accordance with expansion or contraction of the tank. The tank protector is configured to be fixed to an inner side of the band or an outer side of the band.
