    摘要： A propeller blade comprising a composite member. The composite member comprises a stack of plies and a matrix in which the stack of plies is embedded. At least one ply comprises a plurality of first yarns aligned in a first direction defining a plane of the ply and a plurality of second yarns extending transverse to the plane of the ply. Each second yarn does not extend through more than one ply. Also provided is a propelling system comprising the propeller blade, a composite propeller blade prepreg, and a method of forming a propeller blade.

    摘要： A spar for a propeller blade comprises central structural member extending from a root to a tip of the spar. A first portion of the central structural member extends from the root of the spar and a second portion extends from the tip and adjoins the first portion. The central structural member includes a first plurality of plies of composite material on a pressure side thereof and a second plurality of plies of composite material on a suction side thereof wherein the first plurality of plies are in contact with the second plurality of plies in the second portion from a leading edge to a trailing edge thereof. A plurality of yarns extends through the central structural member in at least the second portion.

    摘要： A multi-layer braided article and a method of making the multi-layer braided article. The multi-layer braided article includes a braid extending along a first axis, wherein the braid is folded over itself to form a first layer and a second layer; and a wrapper laid over the first layer of the braid and extending circumferentially around the first axis, wherein the wrapper defines an edge of the first layer about which the braid is folded. The multi-layer braided article may form part of a blade for an aircraft. A sleeve may be provided around a conical portion of the article to connect the article to something else, such as a propeller hub, where the multi-layer braided article is formed as part of a blade. The sleeve may provide a primary or secondary load path.
