China unveiled world's first domestically developed T1200-grade ultra-high-strength carbon fiber on Wednesday, a milestone that fills a critical void in the globe market and marks a major leap forward in the country's advanced materials capabilities, China Media Group reported.

Developed by China National Building Material Group, the newly released T1200-grade ultra-high-strength carbon fiber is not merely a laboratory prototype but an industrialized product already capable of hundred-ton-level mass production, making China the first country in the world to achieve such output capacity for carbon fiber at this grade. 

With a diameter less than one-tenth that of a human hair, the T1200 carbon fiber boasts a tensile strength roughly 10 times that of conventional steel, yet weighs only one-quarter as much - highlighting its exceptional combination of lightness and toughness. 

Thanks to these superior advantages, the material can be widely applied in strategic emerging industries such as aerospace, the low-altitude economy and humanoid robotics.
