3-D FABRICS AND FABRIC PREFORMS FOR COMPOSITES HAVING INTEGRATED SYSTEMS, DEVICES, AND/OR NETWORKS

摘要

A 3-D fabric preform (10) for composites including a three-dimensional engineered fiber preform formed by intersecting yam system components (4, 6, 8); and at least one system, device, and/or network integrated with the preform for providing a predetermined function, wherein the at least one system, device, and/or network is introduced prior to formation of a composite structure including the preform, thereby providing a 3-D fabric preform (10) for composites. Also, a method for forming the 3-D fabric preform for composites including a three-dimensional engineered fiber preform (10) formed by intersecting yam system components (4 6 8); and at least one system, device, and/or network integrated with the preform for providing a predetermined function, wherein the at least one system, device, and/or network is introduced prior to formation of a composite structure including the preform, thereby providing a 3-D fabric preform (10) for composites.
