China’s leading ceramic matrix composite material technology company, XAXY Ceramic Materials Technology Group, developed the “Large and Complex Ceramic Matrix Composite Material Heat-Proof Components Integrated Manufacturing Technology” project, which won the second prize of the 2019 National Technology Invention Award.
For more than 30 years, XAXY has developed a number of ceramic matrix composite materials and participated in the construction of the key laboratory of ultra-high temperature structural composite materials; the research and development team has successively won 1 first prize of national technology invention and 2 second prizes of national technology invention, provincial and ministerial level 4 first prizes for scientific and technological progress, 4 second prizes for provincial and ministerial scientific and technological progress, more than 130 national invention patents…
The ceramic matrix composite material composited with ceramics as the matrix and various fibers has metal-like fracture toughness, is insensitive to cracks, and has no catastrophic damage. It can maintain the excellent properties of traditional ceramic materials such as high temperature resistance, high strength, and low density. At the same time, overcome its fatal weakness of brittleness.
Different from other composite materials, the molding process of ceramic matrix composite materials is relatively complicated, the preparation cycle is long, the cost is high, the requirements for equipment are high, and the yield is difficult to guarantee. Therefore, ceramic matrix composite materials are usually used in special fields, especially in the aerospace field.
Ceramic matrix composite materials are also known as the core material technology for the development of the world’s aerospace industry. When applied to the hot-end parts of aerospace, these materials have absolute advantages in high temperature resistance. Therefore, many countries have already combined ceramic matrix composites. Materials as new strategic materials.
Since obtaining the first ceramic-based composite material patent in 1986, GE has invested nearly US$1 billion in more than 30 years to study how to use this material for mass production within a controllable cost range. The company believes that ceramic-based composite parts that can be used in aero engines include guide blades, fairings, rotor blades, and tail nozzle blades.
XAXY has also gone through nearly 30 years in ceramic matrix composite materials, and the performance of some products even exceeds the international advanced level. For example, we are the leader in ceramic-based composite brakes and aircraft heat protection, but China is still lagging behind in the field of aircraft engines. “
In 2014, the carbon ceramic brake disc project developed by XAXY won the first place in the new material group finals in the China Innovation and Entrepreneurship Competition.
Carbon ceramic brake disc is a new type of brake material developed in recent years. It has the advantages of low density, high temperature resistance, high friction performance and stability. It has a wide range of application prospects in high-energy brake fields such as automobiles, high-speed trains, and aircraft. The cost of XAXY’s carbon ceramic brake discs is only 1/3 of that of similar foreign products, but the performance is higher than that of competitors’ products.
