Recently, according to the news of China Petrochemical Day, the first set of large silk bundle carbon fiber production line of Shanghai Petrochemical Co., Ltd. has achieved mid-delivery (mid-term delivery). Shanghai Petrochemical Co., Ltd. is the first company in China and the fourth company in the world to master the production technology of large filament carbon fiber. The first phase of the project of CCCC has realized the localization of all equipment. What are large bundles of carbon fiber? Usually, the number of carbon fiber roots in each bundle is more than 48,000 (48K for short), which is called large filament bundle carbon fiber.

At present, each bundle of carbon fiber in the domestic basic 1000 to 12,000 between is called a small bundle. The advantage of large filament bundle is that it can greatly improve the productivity and quality performance of carbon fiber single wire under the same production conditions, and achieve low production cost.

In addition, large bundles of carbon fiber has more than 95% carbon content, excellent mechanical properties, less than a quarter of the weight of steel, the strength is 7 to 9 times of steel, and also has corrosion resistance, known as the "king of new materials."

Carbon fiber technology has strong technical barriers, only a few countries such as Japan and the United States have and master. Together with many universities, research institutes and enterprises, Shanghai Petrochemical Co., Ltd. made a major breakthrough in 2018 by successfully trial-producing 48K large fiber bundles and connecting the whole process.

It is understood that when the project is put into production, the single production capacity of the original silk and carbon fiber will be improved, the production cost will be reduced, and the great silk bundle of carbon fiber is completely dependent on imports, in the long-term shortage of supply situation.
