CNT-infused fiber as a self shielding wire for enhanced power transmission line

摘要

A wire includes a plurality of carbon nanotube infused fibers in which the infused carbon nanotubes are aligned parallel to the fiber axes. An electromagnetic shield for a wire includes a plurality of carbon nanotube infused fibers, in which the infused carbon nanotubes are aligned radially about the fiber axes. The plurality of carbon nanotube infused fibers are arranged circumferentially about the wire with the fiber axes parallel to the wire. A self-shielded wire includes 1) a wire that includes a plurality of carbon nanotube infused fibers in which the infused carbon nanotubes are aligned parallel to the fiber axes; and 2) an electromagnetic shield that includes a plurality of carbon nanotube infused fibers in which the carbon nanotubes are aligned radially about the fiber axes. The axes of the carbon nanotube infused fibers of the wire and the carbon nanotube infused fibers of the electromagnetic shield share are parallel.
