Summary Efficient production of carbon fibres using new technologies Innovative process technologies for carbonization of precursor fibres, which can substitute conventional oven technologies and raise the efficiency of carbon fibre production are presented. The process technologies are based on the substitution of convective heat transfer by microwave plasma or direct fiber heating. In microwave‐assisted plasma treatment, the heating of the fibres is carried out both by microwave absorption in the fibre volume and energy input into the fibre surface by means of the plasma species. During electrical carbonization, the fibres are heated by means of an electrical current flow. The processes can be used separately, one after the other (also in combination with conventional furnace technology) or as hybrid processes.
