According to the invention, a method and a plant for the production of fibers, which have a homogeneous, ceramic coating, are provided from a fiber bundle. The method is characterized in that fibers with a homogeneous ceramic layer microstructure and a constant layer thickness can be provided despite high process speeds. The proposed method is based on the approach of decoupling the coating of the fibers with precursors and the pyrolysis of the coated fibers. First, the coating of the fibers with precursors at temperatures <500 ° C and only then the coating is fired at higher temperatures to the ceramic. As a result, a significant increase in the throughput is achieved and the resulting ceramic coatings have fewer defects that otherwise usually occur due to high-temperature-related outgassing of the layers. |
