Let’s give praise and encouragement to the achievements made in China’s chemical engineering technology and equipment; your participation in discussions is the greatest encouragement. **********************【Ten Years of Great Progress in Chemical Engineering Equipment】Continuous updates and summaries available; feel free to join the discussions: https://bbs.hcbbs.com/thread-3576046-1-1.html ***************** On March 11th, the T1200-grade ultra-high-strength carbon fiber, developed independently in China, will make its global debut. This breakthrough fills a gap in this field worldwide, marking a significant advancement for our country in the production of ultra-high strength carbon fibers. The T1200 grade ultra-high strength carbon fiber introduced this time was independently developed by China National Building Materials Group. Notably, it is not a laboratory sample but an industrial product capable of mass production at the hundred-ton level. This also makes our country the first in the world to achieve mass production of carbon fiber at the hundred-ton level at this scale. In simple terms, the diameter of T1200-grade carbon fiber is less than one-tenth that of a human hair, yet its tensile strength is 10 times that of ordinary steel, while its density is only one-fourth that of steel; it thus boasts remarkable lightness and toughness. Thanks to these excellent performance characteristics, it can be widely applied in strategic emerging industries such as aerospace, the low-altitude economy, and humanoid robots.
To date, Zhongfu Shenying has built the world’s first mass-production line for SYT80 (T1200 grade) carbon fiber, achieving localization of raw material formulations, production processes, and all related equipment. Its large-scale production ensures a stable supply of strategic materials for China’s initiatives in deep sea, deep space, underground exploration, and aerospace fields. It will also help reduce the costs associated with the use of carbon fiber materials in areas such as high-speed railways, commercial aerospace, new energy technologies, humanoid robots, and the low-altitude economy.
The successful development of SYT80 carbon fiber was made possible by the mature systems and extensive test data accumulated by the company during the research and development of the SYT45 to SYT70 series of carbon fibers (with tensile strengths ranging from 4500 to 7000 MPa). Chen Qiufei, the project leader, explained that building on their research into the characterization of defects in SYT70-grade carbon fibers and the identification of their causes, the development team focused on key stages throughout the production process, including filament preparation, carbonization processes, and surface treatment. By analyzing the microstructure, they were able to accurately determine the mechanisms behind defect formation and their impact, thereby continuously optimizing process parameters and production methods to minimize the negative effects of defects on the properties of carbon fibers. This approach ultimately led to improvements in the strength of these carbon fibers. Currently, the company supplies high-performance carbon fiber for the casings of four main solid rocket engine models in the commercial aerospace sector. Its SYT70 carbon plate racing shoes, developed in collaboration with Xtep, have successfully captured a niche in the high-end sports equipment market ； SYT45S carbon fiber has contributed to the grid connection of the world’s largest 26MW offshore wind turbine. Currently, enterprises are focusing on emerging fields such as embodied intelligent equipment, and actively promoting the large-scale use of domestic carbon fiber in future industries.
Praise for the achievements in China’s chemical technology and equipment sector
