Recently, after decades of dedicated research, the Shanxi Institute of Coal Chemistry of the Chinese Academy of Sciences, in collaboration with other relevant units, has successfully developed domestically produced T1000-grade high-performance carbon fiber.
This "super-strong material" is now in mass production. Each strand contains 12,000 filaments, each with a diameter less than one-tenth the thickness of a human hair, yet possessing extremely high tensile strength. A one-meter-long carbon fiber strand weighs only 0.5 grams, but has a tensile strength exceeding 6600 megapascals, capable of lifting approximately 200 kilograms without breaking-7 to 8 times stronger than steel.
The reporter visited the birthplace of this carbon fiber and observed the process. After the compounds are polymerized, they are processed through a dry-jet wet-spinning method to form a bundle of filaments. This bundle of filaments looks like common transparent tape, but it actually contains 4,000 filaments. Two to three bundles are twisted together, and each resulting strand contains 12,000 filaments.
Now, this "super-strong material," known as "black gold," is moving out of the laboratory and becoming an indispensable "core component" for national strategic industries such as aerospace, national defense, new energy, and high-end equipment manufacturing.
