Abstract

Une telle pièce est composée d'une double feuille thermoplastique à entretoises intérieures et d'une feuille de mousse de polyéthylène réticulée. La mousse compense les irrégularités de surface produites par le thermoformage de la double feuille et confère à l'ensemble un aspect esthétique, la surface extérieure correspondant exactement à l'empreinte du moule. Si désiré, le côté extérieur de la couche de mousse peut encore être revêtu d'une couche décorative. L'invention est applicable notamment à l'industrie automobile.
