Carbon nanotube-based coaxial electrical cables and wiring harness

1. A method for making a cable, the method comprising:

providing a conducting member defined by one or more yarns extending an entire length of the cable and defined by a plurality of nanotubes continuously intertwined along the entire length of the one or more yarns;

placing a shielding layer circumferentially about the conducting member;

applying a coupling mechanism made from a glassy carbon material between the shielding layer and the conducting member so as to secure the shielding layer in its position about the conducting member; and

heating a material junction between the shielding layer and the conducting member to pyrolyze a glassy carbon precursor to form the glassy carbon material to allow for adhesion and minimize delamination between the shielding layer and the conducting member.

2. A method as set forth in claim 1 , wherein, in the step of providing, includes bonding a plurality of yarns made from the plurality of intertwined nanotubes to create the conducting member.

3. A method as set forth in claim 1 , further including placing a first insulation layer circumferentially about the conducting member.

4. A method as set forth in claim 1 , further including placing an insulation layer circumferentially about the shielding layer.

5. A method as set forth in claim 1 , wherein applying the coupling mechanism includes utilizing glassy carbon material.

6. A method as set forth in claim 1 , wherein the step of placing includes forming the glassy carbon material from a glassy carbon precursor including one of furfuryl alcohol, RESOL resin, PVA, or other liquid resin or material capable of forming the glassy carbon material.

7. A method as set forth in claim 1 , wherein the step of heating includes raising the temperature at the junction to a range of from about 400° C. to about 450° C. or higher to permit the pyrolysis process to go to completion.
