    摘要: A method for designing a composite airfoil (10), comprises designing a mold (32) having an inner surface (32i) that defines a surface profile of the airfoil, defining a preliminary core surface of a woven core (30), wherein the preliminary core surface is offset from the inner surface of the mold (32i) by a specified percentage, filling the space between the mold (32) and the preliminary core surface with a plurality of plies (26) and assembling the woven core (30) and the plurality of plies (26) in the mold (32) and curing to form the composite airfoil (10).

    摘要: According to the method to produce a wind-turbine-blade (BL) a bottom layer (BA) is laid down into a forming tool. The bottom layer (BA) is used as a basis of a pile (PI). A predefined number of additional layers is stacked vertically on top of the basis to form the pile (PI), while the pile (PI) is used as a separate module for the production of the blade. The bottom layer (BA) is made of a nearly airtight material, to prevent that surrounding air is allowed to flow vertically through the pile (PI). An extraction of air is applied by a machine to a topmost layer of the pile in a way that the pile is sucked towards the machine. This allows to lift up the pile and to bring it into a mould for the further production of the blade.

    摘要: A method for manufacturing of a fibre reinforced laminate (13, 15) is provided. The method comprises the steps of:
    a) building up a part (15) of the laminate (13, 15) to a determined thickness using at least one layer of fibre material,
    b) placing a laterally extended layer (13) on top of the partially completed laminate (15), the layer (13) having in a first lateral direction (21) a greater stiffness than in a second lateral direction (22) and having in the first lateral direction (21) a greater stiffness than the other layers constituting the laminate,
    c) building up a new part of the laminate (15) to a determined thickness, and
    d) in case the thickness of the laminate built up pursuant to the steps a)-c) is not as large as a desired thickness of the completed laminate, repeating steps b) and c) until the thickness of the laminate built up is equal to the desired thickness of the completed laminate.
