Abstract

We have formed carbon-copper chloride intercalation compounds using variously graphitized carbon fibers as host materials. The resultant conductors are air stable, thermally stable to 450°K, have electrical resistivities as low as 12.9 μ Ω cm at room temperature, and have metallic conductivity temperature dependencies. These intercalated fibers have tensile strengths of 160 000 psi, and Young's moduli of 25×106 psi. For aerospace use, (resistivity×density)-1 is a figure of merit. On this basis, a reduction in resistivity by a factor of two will make this conductor competitive with copper.
