The invention disclosed herein is an automotive acoustic panel including a porous sound-absorption material made from a polymer and an expanded perlite. One or more silane compounds may be coupled or coated onto the expanded perlite while a coupling agent and a chemical foaming agent may additionally be added to the automotive acoustic panel.

A noise reflector configured to reduce engine sound passing below a side member of a vehicle and leaking laterally from the vehicle. The noise reflector is disposed on a lower side of a lower surface of the side member, has a sound reflective surface tilted from a vertical direction to be directed downward as being gradually laterally distant from an engine, and is configured to reflect downward engine sound received by the sound reflective surface and cause the engine sound thus reflected to interfere with engine sound passing below the side member.

Multilayer sound attenuating trim part for a vehicle, in particularly for a trim part or cladding used in the interior of a car, for instance as an inner dash or as part of the floor covering or for the exterior of a vehicle, for instance as a trim part or cladding in the engine bay area or as part of an under body trim part as well as to the method of producing a part, comprising at least two fibrous layers (10, 30) and at least one air permeable intermediate film layer (20) between the at least two fibrous layers, whereby all layers together have a variable thickness.

A floor structure of an electric vehicle floor structure includes a battery unit and an underfloor panel. The battery unit is arranged underneath a floor of a passenger compartment between front wheels and rear wheels. The underfloor panel covers an entire bottom surface of the battery unit from below. The underfloor panel is provided with a center panel and a surrounding panel. The center panel has a noise absorption material that arranged at a lateral-direction center and a longitudinal-direction center of the underfloor panel. The surrounding panel has a high-strength material arranged around the center panel.

A non-woven fabric board for an exterior of a vehicle and a method for manufacturing same are provided. The non-woven fabric board includes a matrix fiber having a non-circular cross-section and an adhesive fiber having a non-circular cross-section, and the matrix fiber is included in an amount of 50 wt % or greater based on the total weight of the non-woven fiber board. Each of the matrix fiber and the adhesive fiber have a linear density of about 6 to 15 denier and a degree of non-circular shape of about 1.3 to 3.0.

The non-woven fabric board for an exterior of a vehicle has a substantially increased specific surface area by using the non-circular cross-section fibers, improved adhesion efficiency between fibers, and substantially improved mechanical properties. In addition, heat moldability thereof is improved, weight thereof is reduced, and the sound-absorbing performance thereof is substantially improved.

A vehicle undercover mounting bracket for mounting an undercover body is provided. The vehicle undercover mounting bracket includes a frame-side mounting portion mounted on a side rail of a truck frame, an undercover-side mounting portion mounted on the undercover body and spaced apart from the frame-side mounting portion in a longitudinal direction of the side rail, and a connecting portion which extends in the longitudinal direction of the side rail and connects the frame-side mounting portion and the undercover-side mounting portion.

The present disclosure relates to a protective apparatus that can be positioned along an underside of a motor vehicle and, in many cases, near a front or rear region of the motor vehicle. The protective apparatus may include an underbody made from fiber-reinforced plastic for protecting assemblies or components arranged above it against damage as a consequence of stone chipping or ground contact. Further, the underbody may have three-dimensionally structured regions for increasing its rigidity, and the underbody may be designed to absorb chassis and/or crash loads and may include integrated holders for movably attaching chassis links.

A rear wheelhouse vent assembly and a vehicle include a wheelhouse liner. A first edge of the wheelhouse liner defines a cutout that is open along the first edge. The assembly includes a side panel and a duct. The side panel defines a recess, and the wheelhouse liner is disposed along the recess transverse to the side panel to define an open area. The duct is disposed in the cutout. The duct includes a first wall, a second wall and a third wall. The second wall is disposed between the first and third walls. The first and third walls each extend outwardly away from the second wall to respective distal ends to space the second wall from an inner surface of the side panel. The duct is secured to the inner surface and presents a tunnel that vents the open area.

An apparatus and method for improving the safety and performance of an automobile in crash events is disclosed. The apparatus includes a front crash pad, rear crash pad, and a connection beam. Both crash pads and the connection beam are coupled to an automobile in such fashion as to absorb and dissipate energy by converting kinetic energy into strain energy.

According to the present invention, a panel-shaped first metal body (2) comprises a space-forming part (2a) and an overlap part (2b) that is continuous with the space-forming part (2a). A panel-shaped second metal body (4) comprises a space-forming part (4a) and an overlap part (4b) that is continuous with space-forming part (4a). When the first metal body (2) and the second metal body (4) have been assembled, a housing space layer (S1) that is for housing a sheet-shaped glass wool material 3 is formed between the space-forming parts (2a, 4a), and the overlap parts (2b, 4b) overlap. A solid joining part (W1) that connects the overlap parts (2b, 4b) is formed between the overlap parts (2b, 4b).
