Abstract

Ecran (1) de protection acoustique pour moteur de véhicule automobile, ledit écran comprenant un corps (2) en mousse de polyuréthanne moulée élastiquement compressible d’absorption acoustique, ledit écran comprenant en outre un insert (3) poreux à base d’une couche de fibres structurelles, liées entre elles par un agent de liaison, ayant été conformée par thermocompression, ledit insert est surmoulé de part et d’autre par ledit corps de manière à être noyé dedans, de sorte que ledit écran présente deux couches de mousse (4a,4b) séparées l’une de l’autre par ledit insert, ladite mousse ayant pénétré dans au moins une partie de l’épaisseur dudit insert de manière à former au moins une croûte (5) de rigidification et d’étanchéité. Figure 1Acoustic protection screen (1) for a motor vehicle engine, said screen comprising a body (2) of molded elastically compressible sound-absorbing polyurethane foam, said screen further comprising a porous insert (3) based on a layer of structural fibers, bonded together by a bonding agent, having been shaped by thermocompression, said insert is molded on either side by said body so as to be embedded therein, so that said screen has two layers of foam ( 4a, 4b) separated from each other by said insert, said foam having penetrated into at least part of the thickness of said insert so as to form at least one crust (5) for stiffening and sealing.
