ACOUSTIC AND THERMAL SHIELD FOR A MOTOR VEHICLE

The invention relates to a shield comprising: a thermo-compressed porous three-dimensional shell based on glass fibers, the fibers being joined together by a binding agent. The shield includes a foam-based inner spring layer, and additionally has the following features: the foam layer is produced by...

Beschreibung
Zusammenfassung:	The invention relates to a shield comprising: a thermo-compressed porous three-dimensional shell based on glass fibers, the fibers being joined together by a binding agent. The shield includes a foam-based inner spring layer, and additionally has the following features: the foam layer is produced by reaction injection molding (RIM), the layer overmolding the shell. The shell has a porosity arranged in order to enable the foam to penetrate a fraction of the thickness of the shell, so as to create a leaktight skin the binding agent is based on polypropylene. The shell comprises between 45 and 55% by weight of glass fibers.
