Embodiment Construction

[0157] figure 1 A modern wind turbine 1 is shown comprising a wind turbine tower 2, a nacelle 3 arranged on top of the wind turbine tower 2, and a rotor defining a rotor plane. The nacelle 3 is connected to the wind turbine tower 2 eg via a yaw bearing unit. The rotor comprises a hub 4 and several wind turbine blades 5 . Three wind turbine blades are shown here, but the rotor may comprise more or fewer wind turbine blades 5 . The hub 4 is connected via a rotating shaft to a drive train, eg a generator, located in the wind turbine 1 .

[0158] The hub 4 comprises a mounting interface for each wind turbine blade 5 . A pitch bearing unit 6 is optionally connected to this mounting interface and further to the blade root of the wind turbine blade 5 .

[0159] figure 2 A schematic view of a wind turbine blade 5 is shown, which extends in the longitudinal direction from a blade root 7 to a tip end 8 . The wind turbine blade 5 further extends in a chordwise direction from a lea...

Abstract

This invention relates to a wind turbine blade component, a method of manufacturing such a wind turbine blade component and a wind turbine blade comprising the wind turbine blade component. The wind turbine blade component comprising a stack of layers arranged in a first group (30) and in a second group (31), wherein the layers of each group has the same width (W1, W2). The layers of each group iscontinuously offset in an edgewise direction to form a tapered edge profile. The first group (30) of layers may be arranged relative to the second group (31), or in an alternating order. The layers of the first group (30) may further have a first length (L1) which is greater than a second length (L2) of the layers of the second group (31).

Description

technical field [0001] The invention relates to a wind turbine blade component for a wind turbine blade comprising a plurality of layers of fiber material, wherein the plurality of layers comprises a first set of layers and at least a second set of layers Group. [0002] The invention also relates to a wind turbine blade comprising such a wind turbine blade part, and a method of manufacturing a wind turbine blade part. Background technique [0003] It is known to integrate a spar cap or main laminate into the blade shell of a wind turbine blade during the manufacturing process. Alternatively, the main laminate may be attached to the blade shell during a post-moulding process. The main laminates are interconnected via one or more shear webs, I-beams or box beams. It is further known that the main laminate comprises one or more lamination stacks of fibrous material which are impregnated with suitable resins and finally cured. [0004] US 2011 / 0243750 A1 discloses a spar ca...
