Abstract: A method of manufacturing a wind turbine blade shell part is described. Fibre mats and a root end insert are laid up in a mould part in a layup procedure by use of an automated layup system. The fibre mats are laid up by use of a buffer so that the fibre mats may continuously be laid up on the mould surface, also during a cutting procedure. The root end insert is prepared in advance and mounted on a mounting plate. The root end insert is lowered onto the mould by use of the mounting plate and a lowering mechanism. After the wind turbine blade shell has been moulded, the mounting plate is removed.

Abstract: A method of manufacturing a wind turbine blade is described, the blade being formed from at least a pair of blade shells being joined together. For at least a portion of the wind turbine blade, the blade shells are joined by an overlamination applied between the edges of the blade shells, thereby substantially reducing or eliminating the need for a structural adhesive to join the blade shells, particularly in the area of the leading edge of the blade or the root region of the blade trailing edge. The overlamination can be formed from the same material as the blade shells themselves, thereby minimising the possibility of structural faults or cracks due to differences in materials or stiffness levels at the interface between the blade shells.

Abstract: A method for the determination of the deflection of a wind turbine blade is provided. A distance between at least one root location towards a root end of the wind turbine blade and at least one tip location towards a tip end of the wind turbine blade is measured. A blade deflection profile is then calculated based on the measured distance between the root and tip locations and a known modal profile of the wind turbine blade.

Abstract: A blade mould and a method for manufacturing a blade shell part of a wind turbine blade is disclosed. The blade mould comprises a first mould frame; a mould shell supported by the first mould frame and provided with a moulding surface that defines an outer shape of the blade shell part, wherein the mould shell has a longitudinal direction and comprises a root end mould part at a first end thereof; and a first deformation device for deforming the root end mould part of the mould shell. The method comprises arranging reinforcement material on the moulding surface of the root end mould part; deforming the root end mould part to a receiving configuration; inserting the root end insert in the root end mould part; and bringing the root end mould part to a moulding configuration.

Abstract: A hybrid material mat for use in the manufacture of fibre-composite articles, in particular parts for wind turbine blades, is described. The mat comprises a plurality of glass fibre rovings provided on top of a relatively thin planar substrate of carbon fibres. Such a hybrid mat construction provides for an improvement in the structural properties of a component manufactured using the mat, as well as allowing for ease of handling and manufacturing of both the mat itself and the component.

Abstract: A method of manufacturing a composite laminate structure of a wind turbine blade part is performed by resin transfer moulding. The fibre-reinforcement material is impregnated with liquid resin in a mould cavity which includes a rigid mould part having a mould surface defining a surface of the wind turbine blade part. The method includes alternately stacking on the rigid mould part: i) a number of fibre-reinforcement layers including electrically conductive fibres and ii) a flow strip layer in form of a layer of flow strips having a strip width and which are arranged so as to form voids having a void width between two juxtaposed strips. The method includes sealing a second mould part against the rigid mould part in order to form the mould cavity, optionally evacuating the mould cavity, supplying a resin to the mould cavity, and curing the resin to form the composite laminate structure.
