As the “crown pearl of the new material industry”, the carbon fiber industry is a strategic key area for high-tech competition. After years of research and development, China has not only made new breakthroughs in the research and development of carbon fiber materials, its performance index has reached the international advanced level, and it has achieved stable mass production of high-performance carbon fiber, which has provided a powerful development for China's aerospace, transportation and other fields. Material support.

After the complex processes of polymerization, spinning, oxidation, carbonization, etc., these "black filaments" that are being wound up are the newly produced T1000 high-performance carbon fibers. Carbon fiber is a high-strength new fiber material that weighs 1/5 of steel and 5 times stronger than steel. It not only has solid properties, but also soft and processability of textile fibers.

Researcher of Carbon Fiber Technology and Application Center of Hefei University of Technology Zhang Yongming: The raw material of carbon fiber is basically a petroleum product and a component of acrylonitrile. There are many similarities between making carbon fiber and making noodles. In order to ensure that this surface can be well mixed during the polymerization stage, we need to add a lot of components inside, making it easier to be well in the spinning process. Stretch to reduce defects. At the same time, these copolymerization components can be very smooth and stable in the process of carbonization, that is, cooking, so as to ensure that the entire fiber is made of a high performance.

In recent years, China's carbon fiber research has achieved rapid development, and there are more than 40 high-performance carbon fiber engineering research units, but the production process has been facing many problems. After years of research, China's largest high-performance carbon fiber production line has achieved stable mass production, with an annual output of 5,000 tons of raw silk and 1,700 tons of carbon wire. Tested by the authoritative institutions such as the High Performance Carbon Fiber Testing and Evaluation Center of Beijing University of Aeronautics and Astronautics and the National Carbon Fiber Engineering Center of Beijing University of Chemical Technology, its performance indicators have reached the international advanced level such as T700, T800 and T1000.

Researcher of Carbon Fiber Technology and Application Center of Hefei University of Technology Zhang Yongming: Carbon fiber is an advanced material necessary for the development of our national economy. In the future, the car will require a lot of carbon fiber, and we provide a good material guarantee.

According to reports, carbon fiber combined with metal, resin, glass, ceramics and other basic materials, can form high strength, light weight, strong corrosion resistance and other excellent characteristics, widely used in aerospace, transportation, construction and medical, and other fields, Become a strategic new material that affects the future development level of science and technology.
