(FR) DÉCOUPLEUR FIBREUX ACOUSTIQUE
Abstract:
(EN) 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
(FR) L'invention concerne une partie de garniture d'atténuation de bruit tridimensionnelle moulée pour un véhicule, comprenant au moins un système à trois couches constitué d'une première couche fibreuse poreuse et d'une seconde couche fibreuse poreuse et d'une couche de film intermédiaire perméable à l'air située entre les première et seconde couches fibreuses poreuses, et les surfaces adjacentes à l'intérieur du système à trois couches étant reliées entre elles, la seconde couche fibreuse poreuse ayant un poids surfacique AW2 qui varie sur la surface et au moins pour des zones du système à trois couches ayant une épaisseur totale t comprise entre 5 et 35 mm, le poids surfacique AW2 étant lié à l'épaisseur totale t du système à trois couches comme suit, 25*t+175<AW2<45*t+475, où t est en mm et AW2 est en g.m-2, et le poids surfacique AW2 de la seconde couche fibreuse poreuse augmentant avec l'augmentation de l'épaisseur totale t du système à trois couches.
