Japanese new material industry

Japan is far ahead in these three top technologies, putting the rest of the country behind.

The first to bear the brunt is the fifth generation of single crystal material for the latest turbine engine blades. Because the working environment of the turbine blade is very harsh, it needs to maintain an extremely high speed of tens of thousands of revolutions under extremely high temperature and high pressure. Therefore, the conditions and requirements for creep resistance under high temperature and high pressure are very harsh. The best solution for today’s technology is to stretch the crystal confinement in one direction. Compared with conventional materials, there is no grain boundary, which greatly improves the strength and creep resistance under high temperature and high pressure. There are five generations of single crystal materials in the world. The more you get to the last generation, the less you can see the shadow of the old developed countries such as the United States and the United Kingdom, let alone the military superpower Russia. If the fourth-generation single crystal and France can barely support it, the fifth-generation single crystal technology level can only be the world of Japan. Therefore, the world’s top single crystal material is the fifth-generation single crystal TMS-162/192 developed by Japan. Japan has become the only country in the world that can manufacture fifth-generation single crystal materials and has an absolute right to speak in the world market. . Take the F119/135 engine turbine blade material CMSX-10 third-generation high-performance single crystal used in the US F-22 and F-35 as a comparison. The comparison data is as follows. The classic representative of the three-generation single crystal is the creep resistance of CMSX-10. Yes: 1100 degrees, 137Mpa, 220 hours. This is already the top level of developed countries in the West.

Followed by Japan’s world-leading carbon fiber material. Due to its light weight and high strength, carbon fiber is regarded by the military industry as the most ideal material for the manufacture of missiles, especially the top ICBMs. For example, the “Dwarf” missile of the United States is a small solid intercontinental strategic missile of the United States. It can maneuver on the road to improve the pre-launch survivability of the missile, and is mainly used to strike underground missile wells. The missile is also the first intercontinental strategic missile in the world with full guidance, which uses new Japanese materials and technologies.

There is a big gap between China’s carbon fiber quality, technology and production scale and foreign countries, especially high-performance carbon fiber technology is completely monopolized or even blocked by developed countries in Europe and America. After years of research and development and trial production, we have not yet mastered the core technology of high-performance carbon fiber, so it still takes time for carbon fiber to be localized. It is worth mentioning that our T800 grade carbon fiber used to only be produced in the laboratory. The Japanese technology far exceeds the T800 and T1000 carbon fiber has already occupied the market and mass-produced. In fact, the T1000 is just the manufacturing level of Toray in Japan in the 1980s. It can be seen that Japan’s technology in the field of carbon fiber is at least 20 years ahead of other countries.

Once again the leading new material used on military radars. The most critical technology of active phased array radar is reflected in the T/R transceiver components. In particular, the AESA radar is a complete radar composed of thousands of transceiver components. The T/R components are often packaged by at least one and at most four MMIC semiconductor chip materials. This chip is a micro circuit that integrates the electromagnetic wave transceiver components of the radar. It is not only responsible for the output of electromagnetic waves, but also responsible for receiving them. This chip is etched out of the circuit on the entire semiconductor wafer. Therefore, the crystal growth of this semiconductor wafer is the most critical technical part of the entire AESA radar.
