As the latest fifth-generation fighter, the J-20's outstanding performance is obvious to all, and it can approach the target and launch it under the condition that the radar cannot detect, which is enough to prove the strength of the J-20 and its importance. In the face of the mainland's J-20, the United States and the West, including Japan and South Korea, began to be anxious, and even began to "splash dirty water" in various ways.
Not long ago, some Japanese media said: If it were not for Japan's carbon fiber, then China would not be able to manufacture a stealth fighter like J-20. But is this really the case? We used facts to block the mouths of the Japanese media, in fact, our carbon fiber and high-end carbon fiber materials have long been localized substitution and independent production, research and development.
Carbon fiber materials have very important applications in many fields, and can even be said to be one of the indispensable materials, with the title of "outside the material" and "black gold". Carbon fiber materials are not only expensive, scarce and precious, but also have very good performance parameters.
Carbon fiber material weighs only about a quarter of ordinary steel, but it is more than seven times harder and stronger than ordinary materials. At the same time, carbon fiber materials also have excellent resistance to high and low temperatures, as well as oil, acid and corrosion.
With the blessing of this excellent performance and a variety of resistance characteristics, carbon fiber materials are widely used in aircraft, spacecraft and automobile manufacturing and other fields, it can be said that with high strength and lightweight characteristics, carbon fiber has become an ideal lightweight and strengthening material.
The technical threshold of carbon fiber materials is high, and the manufacturing difficulty is also very high, which has led to the fact that only Japan and the United States can manufacture and ship high-end carbon fiber materials in large quantities for a long time. Even with sufficient technology, the production of carbon fiber materials requires a lot of investment, expensive equipment, and a lot of time.
The United States and Japan have previously wanted to erect barriers through technology, materials, equipment, etc., to prevent the mainland from achieving breakthroughs in the field of carbon fiber materials, and the United States and Japan have also been raising the price of carbon fiber materials.
However, in the face of the dependence of carbon fiber materials on imports, the mainland also began to strengthen the research and development of carbon fiber materials in 2000, approved relevant research projects, and began to carry out various research and development and breakthroughs on carbon fiber materials.
In 2005, there were 10 carbon fiber material manufacturers in China, and the production capacity reached 1% of the world's. By 2017, the mainland became the world's third largest carbon fiber manufacturing country, with an annual production capacity of 26,000 tons, accounting for 18%.
After that, in the field of carbon fiber materials, the mainland continued to make breakthroughs, and many carbon fiber manufacturers with excellent production capacity and technology have emerged in China. The most important thing is that in the field of high-end carbon fiber materials, Continental has completed a breakthrough in carbon fiber and graphite fiber materials at the T300 level, T700 and M40 levels.
Up to now, Continental has completed a technological breakthrough in T1000 carbon fiber materials, which is at the world's leading level. This also means that in fact, the mainland has completed the localization of carbon fiber materials, and a large number of carbon fiber materials used in J-20 and other fighters come from domestic production.
According to current domestic reports, the domestic composite materials used in the J-20 are T700-level carbon fiber, accounting for more than 20%, which is much higher than the American F-22, and also exceeds the American T300 material in terms of materials.
The most important thing is that the current domestic carbon fiber production capacity and technology are still in the process of further development and upgrading, even if the supply of carbon fiber materials is really cut off as the Japanese media said, the mainland can also quickly complete the localization of substitution, it can be said that the Japanese media is blocked with factual evidence.
