    Abstract: A method is provided for forming a composite article to have a primary composite structure and an integral secondary composite structure that extends out of a plane defined by the primary composite structure. The method includes laying-up first plies to construct the primary composite structure. The first plies contain continuous reinforcement material and extend from a first zone that will define the primary composite structure into a second zone that will define the secondary composite structure. During laying-up of the first plies, additional plies are interleaved with the first plies within the second zone but not the first zone. The additional plies originate within a build-up zone between the first and second zones and extend therefrom into the second zone. After interleaving the plies, the build-up zone is deformed to orient the second zone and form the secondary composite structure that extends out of the plane defined by the continuous reinforcement material of the first plies.

    Abstract: A fiber preform architecture and method of making, including a plurality of fiber bands. Each band of the plurality of fiber bands is placed at a time, at a predetermined position and orientation, to generate an interwoven and interlocking pattern between the fiber bands. Each of the plurality of fiber bands is formed of a plurality of fiber tows, positioned side by side at a predetermined spacing to define one or more gaps between each tow in the fiber band and define a secondary based interleaving within each of the fiber bands. The plurality of fiber bands are interwoven in an in-plane and out-of-plane orientation by interleaving each of the plurality of fiber bands with one or more of the plurality of fiber bands previously laid down and not in a common plane. The plurality of fiber bands include three or more different orientation angles and provide uniformity in coverage.

    Abstract translation: 纤维预制体结构和制造方法，包括多个纤维带。 多个光纤带中的每个带都被放置在一个预定的位置和方位的时间，以在光纤带之间产生交织和互锁图案。 多个光纤带中的每一个由多个纤维束形成，以预定的间隔并排放置，以在光纤带中的每个丝束之间限定一个或多个间隙，并在每个光纤带内限定二次基交织。 多个光纤带通过将多个光纤带中的每个纤维带与先前放置的多个光纤带中的一个或多个而不是在共同的平面交错而以平面内和面外取向交织。 多个光纤带包括三个或更多个不同的取向角并提供覆盖的均匀性。
