Beschreibung
Zusammenfassung:	A composite part made from a sheet molding compound is disclosed as having improved characteristics over traditional sheet molding compound composite parts. The fibrous material is introduced as a veil layer adjacent a paste layer, the veil flows well during the molding process. The improved flow and surface characteristics of a composite part are attributed to the elongation of the veil during molding and to the improved filling capabilities. L'invention concerne un élément composite fabriqué à partir d'une matière à mouler en feuilles présentant des caractéristiques améliorées par rapport à des éléments composites traditionnels fabriqués à partir d'une matière à mouler en feuilles. Le matériau fibreux est introduit en tant que voile de revêtement à proximité d'une couche de pâte, le voile s'écoulant correctement pendant le moulage. Les caractéristiques de surface et d'écoulement améliorées d'un élément composite sont attribuées à l'allongement du voile pendant le moulage ainsi qu'aux possibilités de remplissage améliorées.
