    Abstract: A method of making a composite rotor yoke includes preparing a molded rotor yoke in a closed cavity tool and possibly machining at least one portion of the molded rotor yoke to form the rotor yoke. In the preferred embodiment, preparing the molded rotor yoke is accomplished by applying layers of uncured low-flow composite material and a layer of uncured high-flow adhesive; substantially enclosing the uncured molded rotor yoke in the closed cavity tool; applying pressure so as to compress the uncured molded rotor yoke; and curing the uncured molded rotor yoke. During the curing process, the high-flow adhesive bleeds out of the molded rotor yoke, thereby preventing marcels from forming through movement of the low-flow composite material.

    Abstract translation: 制造复合转子轭铁的方法包括在闭合腔体工具中制备模制的转子轭，并且可能加工模制的转子轭的至少一部分以形成转子轭。 在优选实施例中，通过施加未固化的低流动复合材料层和未固化的高流动性粘合剂层来制备模制的转子轭铁; 将未固化的模制转子轭基本封闭在闭合腔工具中; 施加压力以压缩未固化的模制转子轭; 并固化未固化的模制转子轭。 在固化过程中，高流动性粘合剂从模制的转子轭中渗出，从而防止通过低流动性复合材料的移动而形成碎屑。

    Abstract: A method of making a rotor yoke includes preparing a cured composite rotor yoke preform on a single-sided curing tool and machining at least one portion of the cured rotor yoke preform to form a rotor yoke. In one embodiment, preparing the cured composite rotor yoke is accomplished by applying successive layers of uncured polymeric composite material to a single-sided tool in a configuration to produce an uncured rotor yoke preform; disposing a semi-rigid caul to an untooled side of the uncured rotor yoke preform; enclosing the uncured rotor yoke preform and the semi-rigid caul by substantially hermetically sealing a vacuum bag to the tool; substantially evacuating a volume defined by the vacuum bag and the tool of air; and heating the uncured rotor yoke preform, sometimes under pressure, to form the cured composite rotor yoke preform.
