Title: ACOUSTIC AND THERMAL SHIELD FOR A MOTOR VEHICLE
Abstract:
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.
