    摘要： A composite spar having an upper and edge regions is provided including a plurality of first laminates and a plurality of second laminates. The plurality of first laminates includes one or more intermediate modulus graphite plies having an intermediate modulus. The plurality of first laminates is arranged in one or more intermediate modulus layers to form at least a portion of the upper wall region, lower wall region, leading edge region and trailing edge region. The plurality of second laminates includes one or more high modulus graphite plies having a high modulus. The plurality of second laminates is arranged in one or more high modulus layers. The high modulus layers are generally interposed between intermediate modulus layers.

    摘要： A composite component such as a blade or vane of a gas turbine engine comprises a body 2 and an erosion-resistant layer 4. The body 2 comprises a fibre reinforcement in a resin matrix, and the erosion-resistant layer 4 comprises a 3-D woven fabric element which is also resin-impregnated. The woven fabric element is made from a thermoplastics material such as PEEK, and may be thicker at the leading edge 6 of the component than at pressure and suction surfaces 8, 10. The component may be manufactured in a laying-up process in which the woven fabric element of the erosion-resistant layer 4 is placed in a mould with the resin-impregnated fibre reinforcement of the body 2 so that the resin of the body 2 migrates into the woven fabric element of the erosion-resistant layer 4.

    摘要： Method for the manufacture of a blade or blade section for a wind turbine, comprising the following steps:
    - providing a mold that can be opened and closed, having an internal cavity with a form corresponding to that of the finished outer surface of a blade or blade section of a wind turbine being manufactured;
    - placing in said mold mechanical means for connecting the blade or blade section, when formed, to another mechanical structure;
    - loading into said open mold a pre-weighed quantity of a chosen plastic or polymer material, in powder or liquid form;
    - closing and rotating said mold, mounted on a respective arm of a rotational molding system, and making the mold rotate around at least one axis;
    - heating said rotating mold to a temperature of between 100°C and 450°C, so that said material uniformly reaches all points of the internal cavity of said mold, settling in layers on the inner surfaces of the mold and gradually forming a hollow body with an external form corresponding to that of said blade or blade section of a wind turbine being manufactured, the final thickness of which is pre-determined by the processing time and by the operating temperature reached;
    - after a pre-determined time and once the material being processed has layered, subjecting the mold to cooling, while said mold rotation continues to prevent deformations of said hollow body;
    - opening the mold, upon completion of the cooling process, in a work station for extracting said hollow body from the mold in a single piece, which has the finished external form of said blade or blade section of a wind turbine, and comprises said co-molded mechanical connecting means inseparably integrated with said hollow body.

    摘要： A propeller blade (10) includes an inner spar structure (16) surrounding an inner spar foam core (14). Also included is a leading edge foam structure (20) disposed proximate a leading edge of the inner spar structure (16). Further included is a trailing edge foam structure (22) disposed proximate a trailing edge of the inner spar structure (16). Yet further included is an outer spar structure (28) surrounding the inner spar structure (16), the leading edge foam structure (20) and the trailing edge foam structure (22). Also included is a blade shell (30), a leading edge foam core (32) located between the outer spar structure (28) and the blade shell (30), and a trailing edge foam core (34) located between the outer spar structure (28) and the blade shell (30).
