(FR) ECRAN DE PROTECTION ACOUSTIQUE ET THERMIQUE POUR VÉHICULE AUTOMOBILE
Abstract: front page image
(EN)The invention relates to a shield (1) comprising: a thermo-compressed porous three-dimensional shell (2) based on glass fibers, said fibers being joined together by a binding agent; a foam-based inner spring layer (3), said shield additionally having the following features: said layer is produced by reaction injection molding (RIM), said layer overmolding said shell; said shell has a porosity arranged in order to enable said foam to penetrate a fraction (4) of the thickness of said shell, so as to create a leaktight skin (5); the binding agent is based on polypropylene; the shell (2) comprises between 45 and 55% by weight of glass fibers.
(FR)L'invention concerne un écran (1) comprenant : une coque (2) tridimensionnelle poreuse thermo-comprimée à base de fibres de verre, lesdites fibres étant reliées entre elles par un agent de liaison; une couche ressort (3) interne à base de mousse, ledit écran présentant en outre les caractéristiques suivantes : ladite couche est issue de moulage par injection-réaction (RIM), ladite couche surmoulant ladite coque; ladite coque présente une porosité agencée pour permettre à ladite mousse de pénétrer une fraction (4) de l'épaisseur de ladite coque, de manière à créer une peau (5) étanche; l'agent de liaison est à base de polypropylène; la coque (2) comprend entre 45 et 55% en poids de fibres de verre.
