Title (EN) SOUND PROTECTION PANEL FOR CLADDING A WALL OF AN AUTOMOTIVE VEHICLE
(FR) PANNEAU DE PROTECTION ACOUSTIQUE DESTINÉ À HABILLER UNE PAROI DE VÉHICULE AUTOMOBILE
Abstract:
(EN) The invention relates to a sound protection panel (1) for cladding a wall of an automotive vehicle, said panel including, in particular so as to form a mass-spring system: a lower spring layer (2) based on a resiliently compressible material; an upper mass layer (3) based on resiliently compressible foam flakes (4), said flakes being bound together by a two-component fibre-based bonding agent (5) comprising a core (6), said core being fusible at a high temperature or infusible, and a sheath (7) fusible at a lower temperature, said flakes being fused with said sheath so as to form an upper agglomerated layer (3).
(FR) L'invention concerne un panneau (1) de protection acoustique destiné à habiller une paroi de véhicule automobile, ledit panneau comprenant, notamment de façon à former un système masse-ressort : une couche inférieure de ressort (2) à base de matériau élastiquement compressible; une couche supérieure de masse (3) à base de flocons (4) de mousse élastiquement compressible, lesdits flocons étant liés entre eux par un agent de liaison à base de fibres (5) bi-composant comprenant une âme (6), ladite âme étant fusible à haute température ou infusible, et une gaine (7) fusible à température moindre, lesdits flocons étant liés par fusion de ladite gaine de sorte à former une couche supérieure (3) agglomérée.
