copper graphite material , is a special material of self-lubricating material, according to the different uses and conditions, choose different copper graphite material
we have silver graphite material too, with high quality and low pricesimpregnated material use mainly 3 types of material: organic resin, inorganic substances and metaland leaching of antimony graphite material can be silicon carbide, tungsten carbide or stainless steel, etcmechanical carbon graphite material is a different kind of graphite material, but with resin /furan /phenolic, metal /copper /antimony or others /silver impregnated
except the carbon brush material, we have other types of graphite material: isostatic graphite, moulded graphite, vibration graphite, extruded graphite, and carbon brush material
pure graphite material will volatile due to volatile substances in the adhesive and binder aggregation, decomposition and carbide, when baking, thus appeared the pore (10% ~ 30% porosity)
resin impregnated material : using synthetic resin (mainly phenolic resin or epoxy resin) impregnated graphite, to fill the surface and internal pore, and then to make the resin curing and heat treatment
main type: m106p，m120p， m254p
antimony graphite material is a kind of excellent self-lubrication antifriction material, it can be in high temperature of 500 ° c, cryogenic – 253 ° c, high speed 20000 rpm, high pressure 10 mpa, or high viscosity medium, especially suitable for medium such as water, oil, kerosene condition under the conditions of useantimony in the case of increasing load and improve the speed and melting steel friction when rare phenomenon, therefore, leach antimony graphite materials can also be applied to medium such as water, hydrochloric acid, strong alkalicurrent products have been widely used in metallurgical continuous casting machine, rolling just equipment, mining machinery, shipping, steam turbine, water turbine, injection molding machine and equipment in the production line

mechanical properties of graphiteit has high bearing capacity, impact resistance, high temperature resistant, self-lubricating ability etcbut the poor thermal conductivity, coefficient of linear expansion; suitable for mass production, the cost is low; mainly used in automobile cooling water pump, low load, such as home appliances sealedwe will serve our customers with the best suitable quality, best delivery time and best solutionsif pure graphite used as sealing ring, it will be permeable or leakage, and strength is low, so we fill the gap increased, and make it not permeability after resin process, it also increased the strengthespecially suitable for overloading, low-speed, reciprocating or swing, difficult to lubrication and oil film formation, not afraid of the water and other acid erosion and erosion
antimony metal does not dissolve in water, hydrochloric acid and strong alkali solutionbut the heat resistance and corrosion resistance have varying degrees of declinewe can produce all sizes /shapes of machined products, like graphite rods, graphite blocks, bipolar graphite plates, sheets…

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 materialceramic matrix composites can be divided into two categories according to the continuity of the reinforcement: continuously reinforced composites and discontinuously reinforced compositesthrough 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 ceramics

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 0it has high strength and high toughnessthe 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 aerospacein 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 worldceramic matrix composites can maintain high stability in high temperature environments, even in aerobic environments, which reduces the development and application costs of thermal protective coatingsIndia
