Abstract
A new class of composites results from a matrix of carbon fibers, including graphite fibers, interwoven in a network of fused metal fibers. The composites can be fabricated to have varying surface area, void volume, and pore size while maintaining high electrical conductivity. Composites are readily prepared from a preform of a dispersion of carbon fibers, metal fibers, and an organic binder such as cellulose, by heating the preform at a temperature sufficient to fuse the metal fibers and to volatilize at least 90% of the binder with a loss of less than about 25%, and usually under 10%, by weight of carbon fiber.
