  • Fiber preform architecture for composite articles and method of fabrication
    Patent number: 9249530
    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.
