Thanks to CTOnews.com netizen love faceless male clue delivery! CTOnews.com October 13 news, according to Sinopec official public number news, October 10, China's first 10,000 tons of 48K large tow carbon fiber project first set of domestic line in Sinopec Shanghai Petrochemical carbon fiber industry base feed drive, and produce qualified products, product performance comparable to foreign products of the same level, quality reached the international advanced level.

This marks that Sinopec's large tow carbon fiber has successfully moved from key technology breakthrough, industrial trial production and industrialization to large-scale and localization of key equipment, breaking the passive situation of carbon fiber production and equipment controlled by others in China at one stroke and truly realizing independent control.

In the carbon fiber industry, the number of carbon fibers per bundle is usually greater than 48,000 (referred to as 48K), which is called large tow carbon fiber. The domestic production line of 48K large tow carbon fiber can realize large-scale and high-quality production. The project adopts PAN (polyacrylonitrile)-based large tow precursor and carbon fiber technology independently developed by Sinopec and is implemented in two stages. It is planned to be completed and put into operation in 2024, when the total production capacity of precursor and large tow carbon fiber will reach 24,000 tons/year and 12,000 tons/year respectively.

Large tow carbon fiber has superior performance and is known as "king of new materials" and "black gold." The large tow carbon fiber developed and produced by Shanghai Petrochemical Company is a new type of high strength fiber material with carbon content above 95%. Its mechanical properties are excellent, the proportion is less than a quarter of steel, the strength is 7 to 9 times that of steel, and it also has corrosion resistance characteristics.

In addition, the biggest advantage of 48K large tow is that under the same production conditions, it can not only greatly improve the single-strand production capacity and quality performance of carbon fiber, but also achieve low production cost, thus breaking the application limitation caused by the high price of carbon fiber.

Where can carbon fiber be used? "King of New Materials" has a wide range of application scenarios, such as wind energy, solar energy, high-speed rail cars, aircraft parts, etc. There are also large tow carbon fibers everywhere in life, including automobile parts, luggage, knee pads, oars, oxygen cylinders...

CTOnews.com understands that for a long time, China's carbon fiber development has mainly achieved breakthroughs in small tow carbon fiber, but due to the high cost of small tow carbon fiber, it has affected the enthusiasm of downstream enterprises to apply carbon fiber. The localization of carbon fiber makes the application of carbon fiber in downstream markets such as new energy gradually erupt. With the continuous improvement of carbon fiber application rate, relevant industries will usher in a long-span high boom stage, which strongly boosts the rapid development of relevant industries and the adjustment of relevant industrial structure in China.

Carbon fiber technology has strict technical barriers. Sinopec is the first enterprise in China and the fourth enterprise in the world to master large tow carbon fiber. After more than ten years of hard work, China's carbon fiber has achieved a major breakthrough from 12K to 48K, successfully realizing the leap from quantitative to qualitative research and development of production technology. Up to now, Sinopec has accumulated 251 patents related to carbon fiber and 46 patents related to carbon fiber composite materials, ranking first in China and third in the world.
