Abstract

A carbon fiber with a conductive finish includes carbon fiber filaments including a metal coating, wherein the carbon fiber filaments have a finish on the metal coating based on at least one polymer binder and containing conductive nanoparticles. The concentration of the metal coating is 8 to 25 wt. % and the concentration of the carbon nanotubes is 0.1 to 1 wt. %, each relative to the weight of the carbon fiber provided with the metal coating and finish. A method for producing fibers of this type is set forth, as well as a fiber-reinforced composite material comprising carbon fibers including carbon fiber filaments, wherein the carbon fiber filaments are coated with a metal, and a polymer-based matrix, wherein the percent by volume of the fibers in the composite material is 30 to 70 vol. % and the composite material additionally contains conductive nanoparticles which are dispersed at least partially in the matrix.
