| 20120100321 | WOVEN PREFORMS, FIBER REINFORCED COMPOSITES, AND METHODS OF MAKING THEREOF - 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. | 04-26-2012 |
| 20110217893 | METHOD FOR WEAVING SUBSTRATES WITH INTEGRAL SIDEWALLS - The present invention generally relates to an integrally woven three-dimensional preform with at least one sidewall in at least one direction constructed from a woven base fabric comprising two or more layers, and a method of forming thereof. A plurality of fibers in a first direction is interwoven between at least the top layer and a second layer, such that top layer is foldable relative to the other layers and form, upon folding, an integral sidewall. A plurality of fibers may also be interwoven between the second-from-the-top layer and a second layer, such that the second-from-the-top layer is foldable relative to the other layers, upon folding, form a second integral sidewall perpendicular to the first integral sidewall. The preform may optionally comprise a plurality of non-integral sidewalls formed by folding portions of the topmost layer. | 09-08-2011 |
| 20110086565 | Woven Preform, Composite, and Method of Making Thereof - A three dimensional woven preform, a fiber reinforced composite incorporating the preform, and methods of making thereof are disclosed. The woven preform includes two or more warp steered fabrics. The warp steered fabrics include a darted portion and an un-darted portion. The darted portions of the warp steered fabrics are joined to un-darted portions of one another so as to provide continuous fiber in the circumferential and radial directions of all portions of the preform. An un-darted portion in one steered fabric reinforces a darted portion in the other. The warp steered fabrics can be woven on a loom equipped with a differential take-up mechanism. The warp steered fabrics can be single or multilayer fabrics. The final preform can be a portion of an aircraft window frame. | 04-14-2011 |
