    摘要: A use of a core block for an impregnation process as well as a composite structure comprising such a core block is described. The core block has a first surface and a second surface, and a number of first grooves is formed in the first surface of the core. Furthermore, a number of second grooves is formed in the second surface of the core. The first grooves have a first height (h1) and a bottom, and the first grooves and the second grooves are part of a resin distribution network formed in the core block. The distance (t) between the bottom of the first grooves and the second surface of the core block is of such a size that the core block is flexible along the first grooves. Additionally, the sum of the first height and the second height is larger than the thickness of the core block, and at least one of the first grooves in the first surface of the core block crosses at least one of the second grooves in the second surface of the core block.

    摘要: A wind turbine blade comprises a profiled contour having a pressure side and a suction side, a leading edge and a trailing edge with a chord extending between the leading edge and the trailing edge. The profiled contour generating a lift when being impacted by an incident airflow is formed by a hollow shell body. The hollow shell body is formed by at least a first shell body part and a second shell body part, which are mutually connected at least at the trailing edge and/or the leading edge. An edge stiffener is arranged within the hollow shell body at a first part of the edges, a first surface part of the edge stiffener being connected to an inner side of the first shell body part, and a second surface part of the edge stiffener being connected to an inner side of the second shell body part.

    摘要: 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.
