Claim Text:
1. A fiber preform architecture for a composite article comprising: a plurality of fiber bands, each of the plurality of fiber bands placed one at a time and discontinuous from all other bands, at a predetermined position and orientation, to generate an interlocking pattern between the plurality of fiber bands, wherein each of the plurality of fiber bands comprise 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, wherein the plurality of fiber tows and bands are at least partially interlocked across one or more planes through a thickness of the fiber preform by interleaving each of the plurality of fiber tows and bands with one or more of the plurality of fiber tows and bands previously laid down and not in a common plane, and wherein the plurality of fiber tows and bands above and below each of the one or more gaps maintain their relative position with respect to each other, to fill the one or more gaps and define a uniformly covered multi-layered assembly, and wherein the plurality of fiber bands include three or more different orientation angles.
