Specialty Fiber for Aerospace, Made in China

Recently, good news comes that the M40J carbon fiber research project hosted by the two hospitals of the Aerospace Science and Engineering Corporation was successful and reached the international advanced level. It indicates that the foreign technical blockade of our country has been breached.

M40J's high modulus carbon fiber has the greatest advantage of being extremely lightweight in manufacturing dimensions, but particularly difficult to deform. Depending on the zero expansion coefficients, it can maintain dimensional stability when subjected to a great temperature difference, neither contracting nor expanding.

High modulus carbon fibers are used primarily in making satellite structures, especially the framework of antennas, rarely used in missiles. Because of the performance and price issues, M series fibers are generally used in the most cutting-edge aerospace technology. In the past, because of the technical blockade, the carbon fiber of the advanced satellite platform in China can only be purchased through non normal channels. Last year, the courts of the U.S.A sued a Chinese citizen, claiming he had smuggled M60J carbon fiber to china.

 At present, China has only realized the localization of M40J and T300, which still lags behind compared with foreign special fiber technology. But the localization of M40J indicates that China has laid the foundation for the research of high-tech special fibers. We believe that with the long-term development of the material industry and science and technology, it is not impossible to break through the blockade. M40J high modulus carbon fibers are expensive materials for making satellite master structures, solar panel supports and antenna scaffolds. When it comes to space science and technology, tungsten is also a very important aerospace science and technology material. Tungsten has excellent physical and chemical properties, such as high melting point, high density, high strength, high conductivity / thermal conductivity, low thermal expansion coefficient, good machinability and corrosion resistance.

High-tech materials M40J high modulus carbon fiber used in the manufacture of satellite main structure, solar panel bracket, antenna bracket, the price is very expensive, when it comes to aerospace materials, aerospace science and technology of tungsten materials is also very important.

Tungsten and tungsten alloys are the main raw materials of space gyroscopes which are accurate instruments for determining the orientation of moving objects. Gyroscope manufacturing technology in China is in the leading position in the world. Learn from the news about successful 10 time’s transfer of culminant star 9A satellite, gyroscope contributes a lot to the success of the satellite technology.

During launch, space rockets require machine parts, engines, and some instruments to require higher heat resistance than ordinary materials. This work is made of non tungsten materials. Tungsten and tungsten alloys are therefore often used as thermal strength materials for space rockets.

Tungsten wire has excellent high temperature resistance and high temperature creep resistance. Its melting point is up to 3380 degrees centigrade. It is used in electromagnetic shielding net.

Zirconium tungstate ceramic is an excellent near zero expansion material, which can better adapt to the space environment. It can be used to manufacture optical instruments, laser devices, optical communication systems and microelectronic devices on satellites.
