Abstract: Disclosed is a wind turbine blade and a method for its manufacture. The wind turbine blade comprises an upwind side shell part, a downwind side shell part, a leading edge and a trailing edge. A flatback web is arranged at the trailing edge, which couples the upwind side shell part with the downwind side shell part, wherein the flatback web comprises at least one U-shaped end section with a recess, into which the upwind side shell part and/or the downwind side shell part is inserted and bonded to the U-shaped end section by an adhesive.

Abstract: Disclosed is a wind turbine blade and a method for its production. The wind turbine blade comprises an upwind side shell part and a downwind side shell part. The upwind side shell part and the downwind side part are bonded together along at least one joint. At said at least one joint, the upwind side shall part and the downwind side shell part are bonded at an internal glue flange as well as at an external glue flange. The glue flange can be produced by using a mould insert along which the glue flange is laminated.

Abstract: The present invention relates to a apparatus for determining at least one a bending strength of a substrate and peel strength of a joint between a structure and the substrate. The apparatus includes a fixture configured to support the structure and a plurality of support beams positioned on either sides of the fixture and configured to support the substrate. Further, the apparatus includes a plurality of load applying members, which are configured to apply load onto the substrate to deform the substrate relative to the plurality of support beams. Furthermore, the apparatus includes a sensor, which is configured to determine parameters such as axial load induced in the structure, peel stress in the joint between the substrate and the structure and bending moments on the substrate during application of load onto the substrate, to determine at least one of the bending strength and the peel strength.
