A material core () for wind turbine blade, comprising: a core body (); a first groove () extending from a first side () of the core body (), in a first direction (), into a depth d1 in the core body (); and a second groove () extending from a second side () of the core body () facing away from the first side (), in a direction opposite to the first direction (), into a depth d2 in the core body (), wherein the second groove () is parallel to the first groove (), and wherein: d2=t−d1+x, 1 mm≤x<d1, wherein t is a thickness of the core body (), and wherein a distance between the first and second grooves is o, wherein: 1 mm≤o≤5 mm.

Material core for wind turbine blade and method for manufacturing the same

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 (). 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.
