Abstract
A woven fiber preform, a fiber reinforced composite incorporating the preform, and methods of making thereof are disclosed. The woven preform includes a plurality of warp and weft yarns or fibers interwoven to form a continuous spiral fabric. The spiral fabric may take the shape of an Archimedes spiral. The weft yarns in the preform may have a uniform or variable pick spacing, or a uniform or variable angular separation. The spiral fabric of the Archimedes spiral may be assembled or wrapped to form a conical shell structure, which could be a portion of a spinner or an exit cone. The spiral fabric may be woven on a loom equipped with a differential take-up mechanism.
