A method for preparing a grease-dispersed zirconium carbide silicon carbide-carbon fiber friction material, characterized in that the graphitized carbon fiber blanket with a density of 0.1-1.8g/ cm3 is carburized, then filled with grease-dispersed zirconium carbide, and then Depositing silicon carbide treatment, then embedding silicon carbide treatment, and then nitriding treatment in a nitrogen atmosphere to obtain a synthetic grease dispersed zirconium carbide silicon carbide-carbon fiber friction material. The present invention uses graphitized carbon fiber blankets to realize the preparation of friction materials through the steps of carburizing, filling zirconium carbide, depositing silicon carbide, embedding siliconizing, and nitriding. The prepared friction material has high strength, high toughness, and high friction performance. It is a friction material suitable for various climatic conditions. |
