Abstract

L’invention concerne un procédé de réalisation d’un écran (1) de recouvrement de moteur de véhicule automobile, ledit procédé comprenant les étapes suivantes : prévoir une couche de lissage (2) à base de mousse de polyuréthanne de masse volumique comprise entre 8 et 15 g/l ; disposer ladite couche de lissage dans un moule de thermocompression, ladite couche étant disposée entre une couche de revêtement (5) et une couche fibreuse (6) destinée à former une coque (7) ; réaliser une compression à chaud de l’ensemble de manière à comprimer ladite couche fibreuse et à comprimer ladite couche de lissage de sorte que son épaisseur devienne inférieure à 1 mm sur au moins 90% de sa surface, de sorte que ladite couche de revêtement ne soit pas marquée par les irrégularités de surface de ladite face correspondante. Figure 1The invention relates to a method for producing a screen (1) for covering a motor vehicle engine, said method comprising the following steps: providing a smoothing layer (2) based on polyurethane foam with a density of between 8 and 15 g / l; disposing said smoothing layer in a thermocompression mold, said layer being disposed between a coating layer (5) and a fibrous layer (6) intended to form a shell (7); perform hot compression of the assembly so as to compress said fibrous layer and compress said smoothing layer so that its thickness becomes less than 1 mm over at least 90% of its surface, so that said coating layer does not is not marked by the surface irregularities of said corresponding face.
