Abstract
Preforms for use in fiber-reinforced composites, fiber-reinforced composites, and methods for making thereof are disclosed. One method includes interweaving a plurality of warp yarns with a single weft yarn so as to form a tubular woven structure with a central axis. The preform can be woven using an endless or tubular weaving technique, and can be woven so as to have two or more diameters along a length thereof. The preform can include one or more layers of a fabric formed on or attached to one or both surfaces of the tubular woven structure. The end structure can be a part of a window frame, a wheel rim, or a combustor in a jet engine.
