Moulded three-dimensional noise attenuating trim part for a vehicle, comprising at least a three layer system consisting of a first porous fibrous layer and a second porous fibrous layer and an air permeable intermediate film layer situated between the first and second porous fibrous layers and wherein the adjacent surfaces within the three layer system are interconnected, wherein the second porous fibrous layer has an area weight AW2 that is varying over the surface and wherein at least for areas of the three layer system with a total thickness t between 5 and 35 mm, the area weight AW2 relates to the total thickness t of the three layer system as following 25*t+175&#x3c;AW2&#x3c;45*t+475 wherein t is in mm and AW2 is in g&#xb7;m&#x2212;2 and wherein the area weight AW2 of the second porous fibrous layer is increasing with increasing total thickness t of the three layer system.

Acoustic fibrous decoupler

Sound absorbing liner for the engine bay of a vehicle comprising at least one fibrous layer consisting of fibers and a thermoset binder thermally moulded to form the liner characterised in that the fibers comprises thermoplastic side by side bicomponent fibers and wherein the sides differ such that the fiber has a frizzy or curved shape.

Lofty thermoset felt for noise attenuation

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 () and at least one air permeable intermediate film layer () between the at least two fibrous layers, whereby all layers together have a variable thickness.

Light weight acoustic trim part

Multilayer automotive trim part for noise attenuation comprising at least two fibrous layers () and at least one air permeable intermediate film layer () between the at least 2 fibrous layers (), whereby the trim part is air permeable, and at least one of the fibrous layers () is a mixture of fibers consisting of 10 to 40% of binder fibers, 10 to 70% of recycled fibers and 10 to 70% of self-crimped fibers and wherein the total amount of said fibers adds to 100% by weight.
