Cmc material introduction
ceramic matrix composites (cmc) are a type of composite material that is composited with ceramics as a matrix and various fibersit is a high-performance composite material formed by implanting high-temperature-resistant continuous ceramic fibers into a ceramic matrix
the manufacturing cycle is long, the cost is high, and the prepared composite material has high porosityceramic matrix composites can greatly improve the reliability and consistency of materials while maintaining the excellent performance of a single ceramic material such as high temperature resistance, high strength, and low densitythe ceramic matrix composite material has a low density (only 1/3~1/4 of the superalloy), and can be used in components such as combustion chambers, regulating plates/sealing plates, and can directly reduce the mass by about 50%
ceramic matrix composites refer to the introduction of reinforcing materials into the ceramic matrix to form a composite

chemical vapor infiltration (cvi)
during the preparation process, the fiber damage is small, the prepared ceramic matrix has high purity and complete crystal form, and the mechanical properties of the composite material are high1-2 μm is deposited on the carbon fiber preform by vapor deposition technology; phenolic resin, carbon black, ethanol, ultrafine silicon carbide powder, polyvinylpyrrolidone and tetramethylammonium hydroxide are prepared in proportion to make a mixed slurry; the slurry is pressurized and impregnated into the above-mentioned carbon fiber prefabricated body in a vacuum environment to obtain a composite material green body; the above-mentioned green body is heated and solidified; the cured green body is placed in a vacuum furnace for high-temperature siliconization reaction to obtain a high-density, high-performance carbon-silicon carbide ceramic composite materialunder the condition of no cooling structure, it can be used for a long time at 1200°c
high stabilitycontinuous fiber reinforced ceramic matrix composites have been widely used in aerospace, national defense and other fieldsin general, it is carried out in conjunction with other methodsin particular, it has a non-catastrophic fracture mode different from that of a single ceramic, which has attracted great attention from researchers all over the world
high temperature resistance
liquid silicon infiltration (lsi)
first, carbon fiber is woven into a three-dimensional fabric (hereinafter referred to as carbon fiber preform); a layer of simple silicon with a thickness of 0the working temperature of ceramic matrix composites is as high as 1650°c, which can simplify or even eliminate the cooling structure, optimize the engine structure, and increase the working temperature of the enginetubes, missile radomes, space shuttle nose cones, aircraft brake discs, and high-end automobile brake discs have become an important branch of the field of composite materialsit has the characteristics of high temperature resistance, wear resistance, high temperature creep resistance, low thermal conductivity, low thermal expansion coefficient, chemical corrosion resistance, high strength, high hardness and wave penetration, and is widely used in many fields such as aerospacethrough the optimization of the preparation process, especially the composition and structure design of the interface layer, the mechanical properties of ceramic matrix composites have been qualitatively improved compared with single-phase ceramicscom/news/ceramic-matrix-composite-cmc-material-professional-manufacturer-in-chinaceramic matrix composites can maintain high stability in high temperature environments, even in aerobic environments, which reduces the development and application costs of thermal protective coatingsit has high strength and high toughnesswith the advancement of fiber preparation technology and other related technologies, people have gradually developed effective methods for preparing such materials, making the preparation technology of fiber-reinforced ceramic matrix composites increasingly mature
excellent mechanical propertiesoverview of ceramic matrix composites——advantages
lightweightceramic matrix composites can be divided into two categories according to the continuity of the reinforcement: continuously reinforced composites and discontinuously reinforced composites
continuous fiber-reinforced ceramic matrix composites are the most outstanding type of materials in ceramic matrix
