What is carbon fiber?

1.The king of new materials in the 21st century

Carbon Fiber is a kind of filamentary carbon material, which is obtained by carbonization and graphitization of organic fiber, with a diameter of 5-10 microns and a carbon content of more than 90%. Carbon fiber has excellent mechanical properties, while with light weight, high strength, high elastic modulus, high and low temperature resistance, corrosion resistance, fatigue resistance and other excellent characteristics, widely used in aerospace, national defense, transportation, energy, sports and leisure fields.

At present, the world's carbon fiber technology is still mainly in the hands of Japanese companies, the production of carbon fiber in both quality and quantity are in the world's leading position, Japan's Toray is the world's high-performance carbon fiber research and production "leader" China's carbon fiber industry as a whole and Japan's carbon fiber research and development synchronous, It has experienced three stages: long-term low level wandering, technological transformation and rapid development. Relying on long-term independent research and development, breaking the blockade of foreign technology and equipment, the industrialization of carbon fiber has made great progress.

2.Market application

Carbon fiber industry is a national strategic emerging industry, with broad prospects for development. The top three areas of global carbon fiber demand in 2021 are wind power blades, sports and leisure, and aerospace, accounting for 28%, 16% and 14%, respectively. Carbon neutrality brings new development opportunities for the carbon fiber industry, creating new demand in areas such as new energy vehicles. Lightweight is an important part of the development of new energy vehicles, and carbon fiber composites comply with the trend of lightweight and are widely used in fuel cells and hydrogen storage tanks.
