The invention relates to a method for producing a liquid container (28) for a motor vehicle, having the method steps: providing a wall (14), which is provided in order to delimit an interior chamber (26) of the liquid container (28) for receiving a liquid (34); providing a structure (2), which is provided in order to be arranged in order to reduce sloshing noises in the interior chamber (26) of the liquid container (28), wherein the structure (2) comprises a random arrangement of threads (4) cross-linked with each other and wherein a plurality of the threads (4) of the structure (2) are integrally joined, at least in sections, to at least one or more additional threads (4) of the structure (2), such that a substantially monolithic structure (2) is formed; connecting the structure (2) to the wall (14).

A high pressure tank of a high pressure tank apparatus includes: a resin-made liner; a reinforced layer covering an outer surface of the liner; and a supplying/discharging hole to which a supplying/discharging flow path is connected via a connecting section. A storage section is capable of storing a leaked fluid that has leaked from the connecting section and a temporary release fluid that has been led out from between the liner and the reinforced layer. A control section, when an internal pressure detection value of the high pressure tank due to a pressure sensor is greater than a threshold value, judges whether the leaked fluid has occurred, based on a detection result of a sensor detecting a concentration of a hydrogen gas inside the storage section, and otherwise does based on a detection result of the pressure sensor.

A tank manufacturing method includes the steps of (a) forming a reinforcing layer before hardening, (b) embedding at least a part of a label into the reinforcing layer before hardening, and (c) winding glass fiber with thermosetting resin before hardening impregnated so as to cover the label to form a surface layer before hardening. The step (a) includes (a1) forming an inner layer before hardening, and (a2) forming an outer layer before hardening having a cover rate lower than the inner layer before hardening and lower than 100%, the outer layer before hardening being arranged on the inner layer before hardening.

A system. The system includes a liquid container and an energy absorbing system positioned. The liquid container includes a wall which defines an interior volume of the liquid container. The energy absorbing system is within an interior volume of the liquid container. The energy absorbing system is configured such that if an object passes through the wall of the liquid container and impacts the energy absorbing system, an amount of energy absorbed by the energy absorbing system is at least 18% greater than an amount of energy absorbed by the wall of the liquid container. The energy absorbing system includes one or more energy absorbing members, wherein at least one of the one or more energy absorbing members comprises a metal and has a Brinell hardness of at least 150.

In a pipe attaching structure of a fuel tank, a pipe attachment section and the fuel tank are molded simultaneously, and the pipe attachment section can be securely molded. In the pipe attaching structure of the fuel tank, which is provided with a pipe attachment section adapted to attach pipes to an exterior wall of the fuel tank, the fuel tank has the pipe attachment section elongating from the exterior wall of the fuel tank outwardly of the fuel tank so as to be integral therewith. The pipe attachment section has an attaching exterior wall composed of the same material with that of the exterior wall of the fuel tank so as to elongate into a cylindrical configuration and continue integrally with the exterior wall of the fuel tank outwardly thereof, and an attaching interior wall formed inside the attaching exterior wall so as to continue from a tip end of the attaching exterior wall and bend like a hairpin, and the attaching exterior wall and the attaching interior wall are brought into contact with each other.

A method for welding a heat shield during manufacturing of a vehicle component made from a thermoplastic material. The heat shield includes: a reinforcement layer made from a thermoplastic material which is weldable to the thermoplastic material of the vehicle component; and a heat shielding material that differs from the thermoplastic material of the reinforcement layer and is configured to decrease transfer of heat through the reinforcement layer to the vehicle component. The method includes: heating the heat shield to bring the thermoplastic material of the reinforcement layer in a molten state; placing the heated heat shield in a mold; bringing into the mold the thermoplastic material of the vehicle component in a molten state; welding the thermoplastic material of the reinforcement layer being in a molten state to the thermoplastic material of the vehicle component being in a molten state, by blow molding the vehicle component in the mold.

A container that provides for control of fluid flow in the event of a failure of the container is disclosed. In accordance with embodiments of the present invention, a container is presented that includes a container wall; and one or more flow impeding structures coupled to the container wall, wherein at least one of the one or more flow impeding structures is a multi-sheet layer that deforms to impede flow in a failure of the container wall. In some embodiments, the multi-sheet layer includes cavities formed between individual sheets.

The invention relates to a tank of plastics material produced by blow-molding of a parison, incorporating a welding spout, of a shape projecting from its outer surface which has an edge configured to be welded to a corresponding edge of an attached part, the welding spout ending axially, on an inside of the tank, in a shape resulting from contact molding between the parison and a molding component, in which the welding spout ends axially on an outside of the tank in a shape resulting from contact molding between the parison and a molding component.

A reinforcement for a tank wall of a vehicle tank includes at least one reinforcing shield for flanking the tank wall, a shield support for supporting the reinforcing shield, and a clamping element. The shield support is axially secured in an axial direction on a clamping element. At least a portion of the reinforcing shield extends in a flank direction transverse to the axial direction.

A method for installing filler tube includes the steps of: preparing a fuel tank including an opening; preparing an intervening member including a cylindrical member body and an annular member flange; preparing a filler tube including a cylindrical tube body and an annular tube flange; arranging the intervening member so that not only the member body is arranged in the interior of the fuel tank through the opening but also the member flange locks to a front-side peripheral face of the opening of the fuel tank; and welding not only the front-side peripheral with the tube flange but also the member flange with the tube flange by arranging a hot plate in a facing space between the front-side peripheral face and the tube flange and then warming the front-side peripheral face, the member flange and the tube flange.
