Abstract

L'invention concerne un écran (1) de protection acoustique pour moteur de véhicule automobile, ledit écran comprenant une coque (2) thermo-comprimée à base de fibres liées entre elles par un liant thermoplastique, de manière à former une coque poreuse pourvue de propriétés d'absorption acoustique, ladite coque comprenant une face interne (3) et une face externe (4), et une feuille (5) métallique lisse de protection thermique vis-à-vis dudit moteur, ladite feuille recouvrant tout ou partie de ladite face interne, ladite feuille étant fixée de façon sensiblement étanche, essentiellement par sa périphérie (6), à ladite coque, de manière à réaliser une étanchéité périphérique et à préserver hors périphérie une lame d'air (8) entre ladite feuille et ladite coque, afin de protéger ladite coque de la chaleur accumulée par ladite feuille.
