Abstract: A wind turbine blade is provided, including two planks joined with each other in a longitudinal direction of the planks at joining surfaces by a butt joint, wherein each plank includes a main portion with a wedge-shaped recess and a wedge-shaped portion filling the recess, each wedge-shaped portion has a respective one of the joining surfaces and is tapered from its joining surface in a direction away from its joining surface, and a stiffness of a material of the wedge-shaped portions is smaller than a stiffness of a material of the main portions. By having the wedge-shaped portions, the load is transferred to the surrounding material over a larger area which reduces the stress concentration.

Abstract: A method for manufacturing a wind turbine blade includes the steps of:



a) arranging a first pre-casted blade segment adjacent to a second pre-casted blade segment,
b) arranging a fiber lay-up in a connection region between the first pre-casted blade segment and the second pre-casted blade segment,
c) covering the connection region with a vacuum cover,
d) applying vacuum to a space covered by the vacuum cover, and
e) infusing the connection region with a resin and curing the resin.




Manufacturing the wind turbine blade by connecting pre-casted segments with each other by vacuum-assisted infusion of resin of added fibers and curing the resin simplifies the manufacturing process. This is in particular the case for very large blades.
