The invention relates to the use of a low Tg compatible resin as an adhesive layer for the welding of a thermoplastic composite structure to a thermoplastic or thermoset structure. The invention is especially good for the welding of large parts, such as wind turbine halves and spar caps. A useful thermoplastic composite is one formed by the infusion and curing of long fibers by a reactive acrylic liquid resin system, such as ELIUM® resin systems from Arkema.

A fuel tank for a motor vehicle includes at least two parts that are joined together, each part being formed by an injection moulding process. The two parts form a receiving chamber for receiving fuel and form at least one other receiving chamber, the receiving chamber and the other receiving chamber being spatially separated by a portion of at least one part.

A plastics container of modular construction includes a first plastics segment and a second plastics segment. The first and second plastics segments are connected to one another by plastics welding. At least one of the first and second plastics segments has a paintable surface layer on an outer side thereof or is comprised of a paintable material.

A system for a motor vehicle, the system including a container having a side made of a plastic material, and a component sealingly attached to the container side. The component has at least one portion provided with microgrooves that form a sealing area between the component and the container side.

An internal support part structure for a plastic tank includes a support rod and end surface components disposed at two ends of the support rod. The support rod is made of a first material. An outer surface of the end surface component is covered by a second material. An outer edge of the end surface component has a regular or irregular shape. The structure resolves a problem that a second material wrapping a first material and connected to an inner wall of a plastic tank may be easily pulled off the inner wall. When a fuel tank is impacted, the support rod of the structure breaks first, to protect the surface of the fuel tank from damage.

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 tank shell as a component of a motorized vehicle tank, where the tank shell includes as wall components a barrier foil and injection-molding material injected thereon at least locally on at least one side, where the tank shell exhibits an aperture configured for the arrangement of a functional component configured with a space section located on an internal side of the tank shell, wherein in a rim region of the tank shell surrounding the aperture there is arranged a socket component which at least section-wise is formed from a material different from the materials of the wall components of the tank shell, where the socket component is connected positively and/or is firmly bonded with the rim region of the tank shell.

A method for producing a compressed gas tank for a motor vehicle includes inserting a bundle of heat-conducting elements through an opening in a housing of the compressed gas tank and exerting a force on the bundle that radially expands the bundle within the housing beyond the size of the opening. The heat-conducting elements may be helically wound about a central axis when inserted through the opening with a torsional force applied to unwind the elements while radially expanding and reducing axial length of the bundle. A compressed gas tank for a motor vehicle includes a plurality of heat-conducting elements including at least one tube within a tank housing that extend axially along the tank and radially within the housing to a size exceeding an opening of the housing. The tube is configured to circulate coolant to cool compressed gas within the tank.

An internal support part structure for a plastic tank includes a support rod and end surface components disposed at two ends of the support rod. The support rod is made of a first material. An outer surface of the end surface component is covered by a second material. An outer edge of the end surface component has a regular or irregular shape. The structure resolves a problem that a second material wrapping a first material and connected to an inner wall of a plastic tank may be easily pulled off the inner wall. When a fuel tank is impacted, the support rod of the structure breaks first, to protect the surface of the fuel tank from damage.
