Woven preforms, for example those used for jet aircraft engine fancases, may need additional stiffeners to improve the strength and/or dynamic performance of the preform assembly, as well as to serve as attachment points. The present invention describes an improved method of manufacturing a woven preform that includes circumferential or axial stiffeners.The preform includes sub-preforms with integral flanges that combine to make integral stiffeners.


Patent
Albany Engineered Composites Inc. | Date: 2015-01-22

A three dimensional woven preform, a fiber reinforced composite incorporating the preform, and methods of making thereof are disclosed. The woven preform includes one or more layers of a warp steered fabric. A portion of the warp steered fabric is compressed into a mold to form an upstanding leg. The preform includes the upstanding leg and a joggle in a body portion. The body portion and upstanding leg are integrally woven so there is continuous fiber across the preform. A portion of the warp steered fabric includes stretch broken carbon fibers in the warp direction, and another portion includes conventional carbon fibers. The warp steered fabric can be woven on a loom equipped with a differential take-up mechanism. The warp steered fabric can be a single or multilayer fabric. The preform or the composite can be a portion of an aircraft window frame.

Woven preforms, for example those used for jet aircraft engine fancases, may need additional stiffeners (502, 503) to improve the strength and/or dynamic performance of the preform assembly, as well as to serve as attachment points. The present invention describes a woven preform that include circumferential or axial stiffenersThe woven incorporates bifurcations in one or more layers (501) of an outermost wrap of a multi-layer fabric (202, 203, 204) composite that forms a preform, wherein the bifurcated outer wrap is folded to form stiffeners that may be oriented circumferentially or axially.

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.

Woven preforms, for example those used for jet aircraft engine fancases, may need additional stiffeners (301, 302) to improve the strength and/or dynamic performance of the preform assembly, as well as to serve as attachment points. The present invention describes several improved manufacturing methods for woven preforms that include circumferential or axial stiffeners. One embodiment includes circumferential stiffeners added to a woven preform. Another embodiment includes sub-preforms with integral flanges that combine to make integral stiffeners. A further embodiment includes an intermediate stiffener wrapped onto a base sub-preform wrap, wherein the intermediate stiffener wrap incorporates intermediate stiffeners. Another embodiment incorporates bifurcations in one or more layers of an outermost wrap of a multi-layer fabric composite that forms a preform, wherein the bifurcated outer wrap is folded to form stiffeners that may be oriented circumferentially or axially.
