In the modern industrial system, alloys are indispensable and important materials for all walks of life. However, compared with traditional alloy metals, in the fields of aero engine blades, new generation fighter fuselages and civil airliners, carbon fiber is far superior to alloys due to its performance and low performance. The quality characteristics are moving towards the trend of becoming a new industrial material in the future.
Recently, China’s high-end carbon fiber has made new breakthroughs. The polyacrylonitrile-based hollow carbon fiber industrialization project led by China’s ZKSX Carbon Fiber Technology Corporation has passed the acceptance. China is also officially listed as the third country alongside Japan and Germany in the field of polyacrylonitrile-based carbon fibers, which means that only these three countries in the world have the ability to produce polyacrylonitrile-based hollow carbon fibers.
New T-1000 grade ultra-high strength carbon fiber
Polyacrylonitrile-based carbon fiber is a new type of T-1000 ultra-high-strength carbon fiber that China has conquered, and it is also a new type of hollow carbon fiber. Its comprehensive performance is better than T800 carbon fiber. It is another important breakthrough in the field of carbon fiber materials in China. Nowadays, looking at the global carbon fiber market, its technology and processing technology are basically monopolized by the United States and Japan.
In the export of T800 and T1000 ultra-high-strength carbon fibers, the companies of the two countries have always maintained a technological monopoly on China. However, in contrast, China is advancing the progress of carbon fiber research and development at the national level. In the field of carbon fiber, it is gradually closing the gap with the United States and Japan. The three male structure of carbon fiber research and production is also brewing.
The “carbon fiber” situation formed by the three major carbon fiber producers in China, the United States and Japan
In the statistics of global carbon fiber production in 2018, China, the United States and Japan accounted for 66% of global carbon fiber production with 35,600 tons, 37,300 tons, and 26,800 tons respectively. It can be seen that China has surpassed Japan in production. However, in the field of ultra-high-strength high-end carbon fiber, the world’s largest carbon fiber company is Japan’s Toray Group, which has become the world’s veritable carbon fiber overlord due to the 50-year order from Boeing of the United States. This is also because Japan has since 1959. The result of the development of carbon fiber technology. Although China started the research and development of carbon fiber in the early 1960s, it was in the 1970s that carbon fiber was born from scratch.
China 863 plans to include high-end carbon fiber research and development
China’s emergence in the global high-end carbon fiber field began when it was promoted by Academician Shi Changxu in the early 21st century and was selected into the National 863 Program in 2002. Since then, Chinese carbon fiber companies have sprung up all over the country, and various types of ultra-high-strength carbon fibers have continued to break through. China’s carbon fiber began to have an impact on the traditional carbon fiber powerhouses, the United States and Japan, and became the third carbon fiber country in the world in one fell swoop. The polyacrylonitrile-based hollow carbon fiber captured by ZKSX this time is only an inevitable result of the development of high-end carbon fiber technology in recent years. Previously, only two companies in the world, BASF of Germany and Toray of Japan, mastered the core technology. The industry is second to none.
China independently developed a new preparation technology of polyacrylonitrile-based hollow carbon fiber
After 2 years of research and development, the new polyacrylonitrile-based hollow carbon fiber has achieved world-leading performance in acceptance. It has become a new type of structure in China by virtue of strong thermal insulation, fine denier and high strength, and a hollow structure with continuous and standardized arrangements. Functionally integrated carbon fiber material. In addition, the development of polyacrylonitrile-based hollow carbon fibers is made by China using the dry-jet wet spinning technology monopolized by the United States and Japan. It is just a new type of dry-jet wet spinning technology created by Chinese researchers through careful research. The polyacrylonitrile-based hollow carbon fiber developed by ZKSX will play an extremely important role in the impact of carbon fiber made in China on the global carbon fiber market.
