Beschreibung
Zusammenfassung:	A turbine blade and a method of manufacturing the wind turbine, wherein the wind turbine blade comprises a composite structure and a surrounding layer. The composite structure comprises a stack of pultruded elements where an infusion-promoting layer is arranged between adjacent pairs of pultruded elements (18). The infusion-promoting layers have a higher permeability than the surrounding layer so that the resin flows at a higher speed within the stacked structure than in the surrounding layer.
