BEIJING, March 11 (Xinhua) -- China debuted its domestically developed T1200 ultra-high-strength carbon fiber on Wednesday, with expected applications in aerospace, low-altitude economy and humanoid robotics.

This new material is not merely a laboratory curiosity, but has achieved a hundred-tonne-level annual production capacity, making China the first nation to mass-produce this caliber of fiber, according to its developer, China National Building Material Group Co., Ltd. (CNBM).

This leap from lab to large-scale manufacturing is expected to accelerate its adoption across high-tech industries.

The fiber's diameter is less than one-tenth that of a human hair, and yet its tensile strength is 10 times that of ordinary steel, and its density is only one-quarter of steel's.
