Beschreibung
Zusammenfassung:	A laminated article (10, 10') includes an optional scrim material (12), a barrier film (14) and a chopped fiberglass layer (16) or a fiberglass mat (16'). The barrier film (14) is extruded and the scrim material (12) and the chopped fiberglass (16) or fiberglass mat (16') are applied to the barrier film (14) while at least a portion of the barrier film (14) is in a molten state. The method of the invention eliminates the need to heat the scrim/barrier film/fiberglass composite in an oven to heat activate the adhesive layers in the barrier film (14), thereby reducing time and cost associated with the manufacturing of the laminated article (10, 10'). Un article stratifié (10, 10') comprend un matériau de canevas (12) facultatif, un film barrière (14) et une couche (16) de fibres de verre coupées ou un voile (16') de fibres de verre. Le film barrière (14) est extrudé et le matériau de canevas (12) ainsi que les fibres de verre coupées (16) ou le voile (16') de fibres de verre sont appliqués sur le film barrière (14) lorsque au moins une partie du film barrière (14) se trouve à l'état fondu. Le procédé selon l'invention évite de devoir chauffer dans un four le composite formé du canevas/film barrière/fibres de verre afin d'activer les couches adhésives du film barrière (14), ce qui réduit ainsi le temps et le coût associés à la fabrication de l'article stratifié (10, 10').
