Abstract: A composite material collation machine and associated method for fiber tape placement and consolidation at a relatively high rate are provided. The composite material collation machine includes a laser diode array for heating at least one fiber tape, a compaction device for pressing the fiber tape against a workpiece, an inspection system for monitoring the fiber tape, and a controller. The inspection system produces an output representative of at least one characteristic of the fiber tape, and the controller is capable of receiving the output and, based on the output, automatically altering at least one system parameter defining an operational characteristic of the composite material collation machine.

Abstract: A connector tow for providing external electrical access to an electrical device embedded within a composite structure. The connector comprises a plurality of tubes disposed between a pair of opposed film layers. The film layers are adhered to opposite sides of the plurality of tubes and can be comprised of an insulating material so as to electrically isolate the plurality of tubes. By extending through the edge surface of the composite structure, the electrical ports can be accessed during the fabrication of the a composite structure such that the operations of the embedded electrical device can be monitored.

Abstract: A method is provided for fabricating a composite structure having an externally accessible electrical device embedded therein. At least one supporting ply is initially provided that has first and second depressions. An electrical device having at least one electrical lead is disposed in the first depression and a connector tow having at least one tube with opposed first and second ends is disposed in the second depression. The first end of the tube of the connector tow is electrically connected to the electrical lead. Thereafter, at least one additional ply is stacked on the supporting ply such that the electrical device and the connector tow are embedded. The stacked plies can then be consolidated to form an integral laminate structure. Following the consolidation, the second end of the tube of the connector tow can be accessed through the edge surface of the laminate structure to thereby define an externally accessible electrical port for receiving a corresponding connector.

Abstract: A composite structure having an externally accessible electrical device embedded therein includes at least one tube disposed within the composite structure and extending from a first end which is electrically connected to an electrical lead of the electrical device to a second end which opens through the edge surface of the composite structure to thereby define an externally accessible electrical port. By plugging a corresponding connector into the electrical port, electrical contact can be established via the electrical lead with the electrical device embedded within the composite structure. By extending through the edge surface of the composite structure, the electrical ports can be accessed during the fabrication of the composite structure such that the operations of the embedded electrical device can be monitored.
