Beschreibung
Zusammenfassung:	The present invention relates to a method for producing a composite part comprising a textured skin and a rigid or foam substrate layer, in particular a composite automotive trim part. The method comprises the steps of spraying or casting an aqueous thermoplastic dispersion onto a rigid or foam substrate composite followed by forming the composite into a composite part comprising a textured skin and a rigid or foam substrate layer. Preferably, the dispersion is derived from the extrusion melt blending of thermoplastic polymer, a dispersing agent, and water. La présente invention concerne un procédé de production d'une pièce composite comprenant une peau texturée et une couche substrat rigide ou expansée, en particulier une pièce composite pour garniture automobile. Le procédé comprend les étapes de pulvérisation ou de coulée d'une dispersion thermoplastique aqueuse sur un composite substrat rigide ou expansé, suivies du formage du composite pour obtenir une pièce composite comprenant une peau texturée et une couche substrat rigide ou expansée. De préférence, la dispersion est obtenue par mélange par extrusion à l'état fondu d'un polymère thermoplastique, d'un agent dispersant et d'eau.
