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.
