With the development of fiber preparation technology and other related technologies, the effective methods to prepare such materials have been gradually developed. It has made the preparation technology of Continuous-Fiber-Reinforced Ceramic Matrix Composite more and more mature. At present, Continuous-Fiber-Reinforced Ceramic Matrix Composites have been widely used in aerospace, national defense and other fields.

Continuous-Fiber-Reinforced Ceramic Matrix Composites have been widely used in the field of aerospace.

Silicon carbide fiber (SiCf) / silicon carbide ceramic (SiC) matrix composites have become a new generation of high temperature resistant materials for Aeroengines. High temperature components of aero-engine mainly include combustion chamber, high or low pressure turbine and nozzle and so on. Among them, high or low pressure turbine components mainly include guide blades, rotor blades and turbine outer rings. In the past, these components were mainly made of superalloys. Its temperature resistance limit is maintained at about 1100 ℃. However, the application of SiCf / SiC ceramic matrix composites improves the temperature resistance of engine components to 1200 ~ 1350 ℃. The components quality of ceramic matrix composites is usually 1/4 to 1/3 times that of superalloys. This not only achieves fuel economy, but also improves fuel economy.

The main preparation technique of SiCf/SiC composites include chemical vapor infiltration (CVI), polymer immersion cracking (PIP) and melt siliconization (MI). In 2015, GE company in US adopted the prepreg infiltration technique to prepare SiCf / SiC composites. SiC fibers can be converted into finished products of any shape in less than 30 days. GE Company successfully verified the world's first rotating low-pressure turbine component on the f414 turbofan engine verification machine. This indicates that the continuous fiber reinforced ceramic matrix composites have a wide application prospect in aeroengines and gas turbines. In May 2021, the first adaptive variable cycle engine xa100 of GE Company was tested. Ceramic matrix composite materials are widely used in this engine, which will provide power for the sixth generation fighter of US. In the 1980s, Safran Group in France began to use CVI Process to prepare rotor blades, mixers and center cones made of SiCf/SiC composite materials. They have been tested on CFM56 engine in the ground test. In addition, the nozzle components have also been flight verified on A320, A380 and other aircraft. The passing of airworthiness certification marks the advent of the era of using SiCf/SiC composite materials for high-temperature components of aeroengines.

Ceramic matrix composites are the key thermal protection materials for the safe flight of hypersonic vehicles. The flight speed of a hypersonic vehicle is greater than or equal to 5 times the speed of sound. In such a high-speed flight, it is necessary to ensure that the key structural components of the vehicle will not be damaged due to intense air friction and hot air flow impact up to 2000 ~ 3000 ℃. 

Fiber-Reinforced Ceramic Matrix Composites have many advantages, such as excellent high temperature performance, high toughness, high specific strength, high specific modulus and good thermal stability, which can effectively overcome the sensitivity to cracks and thermal shock. It also has important applications and a wide market in the field of reusable thermal protection. At present, ceramic matrix composite thermal insulation materials have been developed from a single material to a new thermal protection system combining materials and structures. At the same time, it also develops from the traditional design of heat protection, heat insulation and load-bearing separately to the light direction of heat protection, heat insulation and load-bearing integration.

Fiber-Reinforced Ceramic Matrix Composites have many excellent properties such as high temperature resistance, ablation resistance, high strength, low dielectric, low loss and high reliability. They should be the key material of radome, which is one of the bottlenecks and difficult technologies in the development of new missiles and combat aircraft. At present, there are mainly composites such as quartz, fiber-reinforced quartz ceramics, quartz fiber-reinforced silicon nitride ceramics, nitride fiber-reinforced silicon nitride ceramics and so on. They all have excellent comprehensive properties such as high temperature resistance, wave transmission, bearing & heat release and so on. During the period from 2016 to 2020, Shandong industrial ceramics research and Design Institute Co., Ltd., has carried out systematic research on continuous nitride fiber fabric and nitride chopped fiber reinforced silicon nitride composite system. The composite material developed by the company has excellent ablation resistance, excellent dielectric properties and good mechanical properties. Under the condition of high heat flux and enthalpy, it can withstand high temperature of 2700 ℃ and long-term ablation test. It should be a new generation of ceramic wave transmitting composite material that can meet the requirements of high speed, long endurance, low ablation and high wave transmission in the future.

It has developed rapidly in the civil field.
