摘要:
The invention relates to a 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.
摘要:
An undercover is provided which can have an electromagnetic shield effect in a vehicle including a battery unit and an electric motor for driving. The battery unit is provided at a lower portion of a car body. The undercover is provided under the battery unit. The undercover functions to prevent an obstruction or a stone leaping during driving from directly hitting on a battery case, and smoothens a flow of air in an area under the car body during driving. The undercover (20) includes an undercover body (81) and a cloth electromagnetic shield member (86) formed of a conductive fabric (85). The conductive fabric (85) is soft and flexible, and is molded along with the undercover body (81), with resin (80) of the undercover body (81) heated, so that they unite with each other. The resin (80) is melted and stuck to the conductive fabric (85) to obtain an anchor effect, as a result of which the conductive fabric (85) is fixed to the resin (80) of the undercover body (81).
摘要:
Wheel arch liner for a vehicle, comprising at least a fibrous layer comprising of thermoplastic bicomponent filaments, consisting of a first polymer forming the core of the bicomponent filament and a second polymer forming the sheath of the bicomponent filament, whereby that the sheath of the bicomponent filament comprises at least one repellent additive of fluorinated or per-fluorinated short chain molecules with a chain length in the range of C4-C14 and whereby the fibrous layer is consolidated by heating thereby melting the sheath polymer forming binding points between the filaments and redistributing the repellent additive forming a liquid repellent consolidated fibrous layer.

摘要:
An exterior trim part for a vehicle comprises a fibrous porous structural layer. The fibrous porous structural layer consists of staple fibres, only. At least 50%, preferably between 70% and 100%, of the staple fibres comprise a first polymer made of modified polyester, such as CoPET, with a melting temperature between 150°C and 240°C, preferably between 190°C and 240°C.

The invention relates to an underbody panelling part of a wheel axle near the wheelhouse (18) of a motor vehicle (12), which underbody panelling part comprises a main part (22) the covering surface of which is variable and which has a fastening structure for fixed connection to the body and/or a fastening structure (34) for fixed connection to a transverse link of the motor vehicle (12). In the mounted state the covering surface can be varied with the steering angle.
摘要:
In accordance with a first aspect of the invention, the exterior trim part for a vehicle comprises a fibrous porous structural layer. The exterior trim part further comprises at least one at least sectional perforated film layer, which is made of thermoplastic polyurethane with a melting temperature according to DSC of at least 140°C. The film layer is materially connected to the fibrous porous structural layer, at least in sections.
