Description

technical field [0001] The invention relates to a preparation method of a friction material composited by carbon fiber and ceramic material, and belongs to the technical field of composite material preparation. Background technique [0002] At present, carbon fiber and carbon (C / C) composite materials are mainly used as friction materials. Since the wear resistance of C / C composite materials is relatively low, people are looking for a method for preparing friction materials with higher wear resistance. In addition, the friction performance of C / C composite materials will be reduced in a humid environment, which will bring serious safety hazards to the use. Contents of the invention [0003] The object of the present invention is to provide a method for preparing a friction material that can overcome the above-mentioned defects, achieve higher strength, higher friction performance and adapt to various climatic conditions. Its technical solution is: [0004] The preparatio...
