A composite interconnect assembly includes a body structure formed from a composite material (e.g., a carbon graphite material) with one or more conductive traces embedded therein (e.g., a copper or copper alloy). One or more contact regions are provided such that the conductive traces are exposed and are configured to mechanically and electrically connect to one or more electronic components. The body structure may have a variety of shapes, including planar, cylindrical, conical, and the like.

1. A composite interconnect assembly, comprising: a generally tubular, composite body structure comprising layers of two or more constituent materials having different physical and chemical properties;a conductive trace embedded within the composite body structure at a border between the layers, the conductive trace traversing the border such that a portion of the conductive trace only partially intrudes into and forms at least three contact surfaces with one of the layers and an opposite portion of the conductive trace only partially intrudes into and forms at least three contact surfaces with the other of the layers; anda contact region defined on the composite body structure such that the conductive trace is exposed and is configured to mechanically and electrically connect to an external electronic component,wherein one of the two or more materials of the composite body structure is a carbon graphite material. 2. The composite interconnect assembly of claim 1, wherein the composite body structure has a thickness of less than approximately 1.5 mm. 3. The composite interconnect assembly of claim 1, wherein the conductive trace comprises copper. 4. The composite interconnect assembly of claim 1, wherein the contact region is an opening in the composite body structure extending to the conductive trace. 5. The composite interconnect assembly of claim 1, wherein the contact region is a bond pad substantially flush with the composite body structure. 6. The composite interconnect assembly of claim 1, wherein the contact region is a through-hole structure. 7. The composite interconnect assembly of claim 1, further comprising electrical components disposed radially from the outer perimeter of the tubular, composite body structure toward an interior of the tubular, composite body structure. 8. The composite interconnect assembly of claim 1, further comprising a plurality of conductive traces configured within multiple levels. 9. A composite interconnect assembly, comprising: a composite body structure comprising at least two layers, with each layer comprising two or more constituent materials having different physical and chemical properties;a conductive trace embedded within the composite body structure at a border between the layers, the conductive trace traversing the border such that a portion of the conductive trace only partially intrudes into and forms at least three contact surfaces with one of the layers and an opposite portion of the conductive trace only partially intrudes into and forms at least three contact surfaces with the other of the layers; anda contact region defined on the composite body structure such that the conductive trace is exposed and is configured to mechanically and electrically connect to an external electronic component,wherein one of the two or more materials of the composite body structure is a carbon graphite material. 10.
