A fuel tank of an advanced ballistic tolerant fuel containment system is constructed with an inner layer designed to contain fuel, an intermediate layer or layers designed to self-seal any openings or holes made into the fuel tank, and an exterior layer that reinforces the fuel tank and provides the fuel tank with hard points for connection to an aircraft or vehicle. The interior layer, the intermediate layer and the exterior layer are all constructed of thermoplastic materials.

A fuel tank comprises a circular column-shaped fuel tank body, a handle, and a lock mechanism. The circular column-shaped fuel tank body is provided so as to be capable of being detachably attached to a fuel-powered device. The handle is formed on one end side in a length direction of the fuel tank body. The lock mechanism is capable of switching between a locked state in which the fuel tank body cannot be removed from the fuel-powered device, and a lock-released state in which the locked state has been released, due to the fuel tank body being rotated in a circumferential direction in a state of being installed to the fuel-powered device.

A fuel tank in a vehicle. The fuel tank includes a protective outer shell and an inner shell. The protective outer shell has an inner shell receiving area. The inner shell, which holds fuel, is housed in the inner shell receiving area of the outer shell. The inner shell cooperates with the outer shell to maintain the position of the inner shell relative to the outer shell and relative to the vehicle during normal operation. During an impact to the vehicle, the inner shell moves independent of the outer shell and the vehicle, allowing a portion of the energy or the forces associated with an impact to be absorbed by the outer shell, reducing the energy or force transferred to the inner shell.

A method for forming a welding spout of a plastic tank from a multilayer parison, during blowing of the parison for manufacturing the tank. The method includes, in a blowing mold including two cavities and an insert, one of the cavities delimiting a recess for forming the welding spout, the recess having a mouth opening opposite the insert: providing a push member on the insert opposite the mouth of the recess of the cavity, capable of assuming a first position set back from the recess and a second position in which the push member occupies a portion of the mouth of the recess; positioning the push member in the first position thereof; blowing the parison to match a shape of the cavities; during creeping of the parison towards the inside of the recess, moving the push member into the second position thereof.

A fabric coated or impregnated with an elastomeric material may include a polyurethane dispersion layer combined with a sealant. The fabric may be applied in such a fashion so as to enable the elimination of solvent or fluid that is associated with the elastomer. The polyurethane dispersion layer generally comprises an elastomeric material dispersed or dissolved in a liquid medium, such as, but not limited to, water. At the same time, the integrity of the elastomeric composite which is formed from the dispersion and sealant layers may be maintained in order to minimize the presence of air voids and pockets. It has thus been realized that in doing so the performance of the self-sealing volume is dramatically improved. This method of construction usually may be accomplished without significantly adding to the weight or thickness of the volume and without affecting the outer dimension of the self-sealing volume.

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.

An exemplary fuel tank includes a plastic container and an integral composite heat shield. The plastic container has an outer layer formed from high-density polyethylene. The heat shield has a heat reflective layer, an attachment layer, and a non-woven insulation layer having a bonding portion that includes bi-component fibers. The outer layer of the plastic container permeates and bonds to at least a portion of bonding portion of the non-woven insulation layer.

A fuel system component used to supply a fuel to a fuel tank or used to discharge the fuel from the fuel tank comprises a first resin layer; and a second resin layer formed in a similar color to that of the first resin layer and configured to include a welding portion that is welded to the first resin layer and an exposed portion that is not adjacent to or in contact with the first resin layer. A belt-like portion is formed on a first resin layer-side and conically shaped surface of the exposed portion of the second resin layer at a distance from a boundary between the welding portion and the exposed portion and is configured to include at least one of a concavity and a convexity extended intermittently or continuously.

In a method of producing an automobile fuel tank including a tank body, an outer wall of the tank body being formed of a synthetic resin layer composed of a multilayer configuration, wherein the synthetic resin layer includes an inner body layer and an outer body layer with at least a barrier layer interposed therebetween, and the inner body layer includes a structural member with an air space internally provided, the method includes: forming the outer wall of the inner body layer, the outer body layer, and the barrier layer which is interposed between the inner body layer and the outer body layer, exclusive of the structural member; and welding the structural member only to an inner face of the inner body layer.

Methods and systems described herein provide or use a wall structure for a hydrocarbon storage vessel. The wall structure includes an inner layer comprising a first rubber compound, a center layer comprising a fabric having a barrier layer applied to each side, and an outer layer comprising a second rubber compound.
