    摘要： A blank sheet (7) including a plurality of main fibers (71) arranged in parallel with each other, auxiliary fibers (72) and a resin that consolidates the fibers is heated to a temperature at which the resin softens, and then pressed against a fan blade mold (6b) with the direction of the main fibers (71) aligned with the longitudinal direction of the fan blade mold (6b). The fan blade mold (6b) is shaped so that the length thereof in the longitudinal direction along the surface of a center part (64x) thereof in the width direction is shorter than the length thereof in the longitudinal direction along the surface of end parts (64y) thereof in the width direction. When the blank sheet (7) is pressed against the fan blade mold (6b), a center part (7x) in the width direction of the blank sheet (7) at an end part (7a) in the longitudinal direction is pulled with a greater force than end parts (7y) in the width direction of the blank sheet (7) at the end part (7a) in the longitudinal direction, thereby preventing occurrence of wrinkling.

    摘要： A method for manufacturing a component (5) for a wind turbine is provided.
    The method comprises: a) covering a mold surface (9) with a peel-off layer (10), b) providing a layup (13) of fiber material on top of the peel-off layer (10), c) curing a resin impregnating the fiber material to form the component (5), and d) peeling the peel-off layer (10) off the component (5).
    The method is advantageous in that it avoids sanding or sandblasting of a cured blade to remove a release agent adhering to the blade surface.

    摘要： The invention relates to a method for producing a fibrous preform for the manufacture of a turbomachine blade made of composite material, the method involving using three-dimensional weaving to create a fibrous rough form (100) in a single piece with layers of longitudinal threads (c
    1 to c
    24 ) joined together by threads of layers of transverse threads (t
    1 to t
    24 ), and shaping the fibrous rough form to obtain a fibrous preform in a single piece having a part that forms the aerofoil preform and at least a part that forms a platform preform. During the course of the weaving process, the threads (c
    5 to c
    7 ) of a first group of longitudinal threads are led out from the fibrous rough form on the side of one of the lateral faces (110a) of the rough form to form a part (120) that corresponds to a preform of a blade platform, and threads (c
    3 and c
    4 ) of a second group of longitudinal threads are injected into the fibrous rough form with mutual criss-crossing between the threads of the first group and the threads of the second group. The invention also relates to a preform obtained using this method.
