Abstract: The present invention relates to an embedding element (76) for embedment in a shell structure of a wind turbine rotor blade (10), the element having a wedge-shaped part (85). The embedding element (76) 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 (76), to a method of manufacturing a wind turbine rotor blade (10) using the embedding element (76), and to a wind turbine blade (10) obtainable by said method.

Abstract: 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 (16) is placed on a mould surface (14) and a distribution layer (24) is placed above the fibre lay-up (16). At least one segmentation area is provided in the distribution layer by providing at least one transversely extending flow barrier in the distribution layer (24) preventing or restricting longitudinal resin flow to the distribution layer. A longitudinally extending first feed channel (27) is placed above the distribution layer (24). The first feed channel (27) is divided into at least two feed channel sections, a feed channel section being arranged in each distribution layer segment. A vacuum bag (43) is arranged on top of the mould part (13) to define a mould cavity. The mould cavity (44) 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.
