The present invention aims to provide a sound-absorbing material having sound absorption performance with an average sound absorption coefficient of 0.65 or more in the frequency domain of 800 to 2000 Hz. The present invention relates to a sound-absorbing material including: a fiber layer including a plurality of holes open to a surface thereof and having a thickness of 3 mm or more; and an inorganic material layer formed on the surface of the fiber layer, the holes being blind holes each penetrating through the inorganic material layer and having a bottom inside the fiber layer.

Provided is a vehicle front structure capable of, without breaking a lid provided at a thermal insulating cover, reliably closing a bonnet and the lid even if an attempt is made to close the bonnet prior to closing the lid. In the present invention, a thermal insulating cover 10 including a lid 30 that covers the upper side of an engine in an openable and closable manner is provided below a bonnet 1 that covers the upper side of an engine room in an openable and closable manner; the lid 30 is provided with, in the vehicle front-rear direction, a hinge fulcrum 36 on the same rear end side as a hinge fulcrum 4 of the bonnet 1 and is openable and closable independently of the bonnet 1; and the lid 30 includes locking means 40 that is locked to the bonnet 1 when the lid 30 is open and is released from the locking in conjunction with a closing operation of the bonnet 1.

A weather shield for covering an engine bay of a vehicle, such as a C8 corvette. The weather shield protects the engine and other components in the engine bay from water and sunlight. The shape of the weather shield allows water coming from rain or car wash to channel to drain holes in the engine bay.

A vehicle includes an internal combustion engine, a supercharger placed behind an internal combustion engine, and a first insulator and a second insulator covering the supercharger. The first insulator is provided between the internal combustion engine and the supercharger and covers the supercharger from its front side. The second insulator covers the supercharger from its upper side, its rear side, and its lower side. An upper edge of the first insulator and an upper edge of the second insulator are positioned above and ahead of the supercharger and define a first opening. The first opening faces forward when the first opening is viewed from an inner region surrounded by the first insulator and the second insulator.

Disclosed are an undercover for vehicles with high elasticity and rigidity and a method of manufacturing the same. The undercover for vehicles with high elasticity and rigidity may include a needle-punched nonwoven fabric having a multi-layer structure of felt layers including a first PET fiber and a low-melting-point PET fiber, and each of the felt layers may have improved tensile strength and have optimized fiber alignment, to thereby improve the binding between fibers, mechanical rigidity and elasticity, as well as to reduce the weight of components, improve durability and secure harmlessness and inline workability.

It is described a metamaterial sound insulation device, with improved efficiency in dampening sound transmission across it compared to a traditional sound insulation device having comparable size and weight. The device is especially adapted for sound insulation in the automotive field.

A cover member (1) includes a curved upper surface (U1) that covers an upper wall portion (U) of a radiator grill (R) from above, wherein the curved upper surface (U1) includes a sealing material dispositioning region (R1) in which a foam sealing material (S) is provided and which is surrounded by a frame-shaped protruding portion (1b), and a sealing material non-dispositioning region (R2) disposed adjacent to the sealing material dispositioning region (R1), in which the foam sealing material (S) is not provided, and a maximum curvature (C1) of the upper surface (U1) in the sealing material dispositioning region (R1) is set to be smaller than a maximum curvature (C2) of the upper surface (U1) in the sealing material non-dispositioning region (R2).

A cover for integrated power electronics (IPE), the cover including a first sheet, a second sheet bonded to the first sheet by at least one joining point in a perimeter region, a cavity defined between the bonded first sheet and second sheet, wherein the perimeter region seals the cavity, and a filler material disposed within the cavity.

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.
