A shear web mould system for manufacturing a wind turbine component in form of an I-shaped shear web having a web body and a first web foot flange at a first end of the web body and a second web foot flange at a second end of the web body is described. The system comprises a central moulding portion for forming at least a part of the web body, a first moulding plate for forming at least a part of the first web foot flange, and a second moulding plate for forming at least a part of the second web foot flange. The angles of the first moulding plate and the second moulding plate relative to the central moulding portion are adjustable.

A wind turbine blade () for a rotor of a wind turbine () having a substantially horizontal rotor shaft is described. A surface mounted device () is attached to a surface of the wind turbine blade (). The surface mounted device () is attached to the surface of the wind turbine blade () via at least a first attachment part ('), which is connected to a part of the surface mounted device (). The attachment part (&#x2032;) comprises a flexible housing () that forms a cavity () between at least the housing () and the surface of the wind turbine blade (). The cavity () is filled with an adhesive that provides an adhesive bonding to the surface of the wind turbine blade ().

The present invention relates to an embedding element () for embedment in a shell structure of a wind turbine rotor blade (), the element having a wedge-shaped part (). The embedding element () comprises a fibre material and a binding agent, wherein the fibre material is at least partially joined together by means of the binding agent. The inventive element provides improved structural flexibility and elasticity resulting in less wrinkle formation during blade manufacturing. In other aspects, the invention relates to a method of manufacturing the embedding element (), to a method of manufacturing a wind turbine rotor blade () using the embedding element (), and to a wind turbine blade () obtainable by said method.

A method of manufacturing a wind turbine blade component in form of a shear web is described. The method comprising the steps of: a) providing a pre-manufactured shear web body having a first side and a second side as well as a first end and a second end; b) providing a first pre-formed web foot flange comprising a fibre-reinforcement material; c) arranging a first fibre layer from the first pre-formed web foot flange and to a part of the first side of the shear web body; d) arranging a second fibre layer from the first pre-formed web foot flange and to a part of the second side of the shear web body; e) supplying a resin to said first fibre layer and second fibre layer simultaneous with or subsequent to steps c) and d); and f) allowing the resin to cure so as to form the shear web.

In a method of manufacturing a blade shell half of a pre-bent wind turbine blade by means of vacuum-assisted resin transfer moulding (VARTM), a fibre lay-up () is placed on a mould surface () and a distribution layer () is placed above the fibre lay-up (). At least one segmentation area is provided in the distribution layer by providing at least one transversely extending flow barrier in the distribution layer () preventing or restricting longitudinal resin flow to the distribution layer. A longitudinally extending first feed channel () is placed above the distribution layer (). The first feed channel () is divided into at least two feed channel sections, a feed channel section being arranged in each distribution layer segment. A vacuum bag () is arranged on top of the mould part () to define a mould cavity. The mould cavity () is evacuated and liquid resin is supplied to each feed channel section through a resin inlet to fill the mould cavity and impregnate the fibre lay-up.
