Research progress in brazing of fiber-reinforced ceramic matrix composites and metals#br#

Fiber-reinforced ceramic matrix composites show superior performance over traditional ceramic materials in terms of high temperature serviceability. The components joined with metals have great potential application in high temperature systems, such as aerospace, nuclear energy, chemical industry. The joining technology of fiber-reinforcement ceramic matrix composites and metals has been studied extensively, among which brazing is the best choice. This paper focuses on the challenges and scientific issues of brazing fiber-reinforced ceramic matrix composites with metals. The most widely studied examples of brazing of fiber-reinforced ceramic matrix composites and metals, such as C_f/C, C_f/SiC, SiO_2f/SiO₂, are discussed. The latest research results of the wetting behavior of braze, the regulation of interface reactions, and the adjustment of joint stress are investigated. The development of reliable joining technology will promote the research and application of more fiber-reinforced ceramic matrix composites with excellent performance.
