Beschreibung
Zusammenfassung:The invention relates to a conductively furnished carbon fibre, consisting of carbon fibre filaments which have a metal coating, the carbon fibre filaments having a preparation which is located on the metal coating and is based on at least one polymeric binder, said preparation comprising conductive nanoparticles, the concentration of the metal coating being 8 to 25 wt% and the concentration of the carbon nanotubes being 0.1 to 1 wt%, based in each case on the weight of the carbon fibre provided with the metal coating and preparation. The invention further relates to a method for producing such fibres and also to a fibre-reinforced composite material, comprising carbon fibres consisting of carbon fibre filaments, the carbon fibre filaments being coated with a metal, and to a polymer-based matrix, the fibre volume fraction in the composite material being 45 to 70 volume % and the composite material further comprising conductive nanoparticles which are present at least partly in dispersion in the matrix.
