Carbon fiber is an inorganic polymer fiber containing more than 90% carbon, which is formed by pyrolysis and carbonization of organic precursor fibers at a high temperature of 1000°C to 3000°C in an inert gas atmosphere. From the molecular structure point of view, carbon fibers can be seen as graphene arranged along the fiber axis. Its mechanical, chemical and electrical properties are excellent, and it is an indispensable strategic new type material for national economic and national defense construction. It is known as “black gold”.

▲Main carbon materials

Carbon fiber has excellent corrosion resistance to common organic solvents, acids, and alkalis. It is insoluble and intumescent, and its corrosion resistance is outstanding. There is no problem of rusting at all. With its characteristics of high strength, high modulus, low density, small linear expansion coefficient, and corrosion resistance, carbon fiber is the king of new materials and is well-deserved.

▲Excellent physical and chemical properties of carbon fiber

Carbon fiber is the fiber with the highest specific strength and the highest specific modulus among the high-performance fibers that have been mass-produced at present, and has low density, corrosion resistance, high temperature resistance, friction resistance, fatigue resistance, high vibration attenuation, electricity and heat High conductivity, low thermal and wet coefficient of expansion, high X-ray penetration, non-magnetic but electromagnetic shielding effects, etc., are important strategic materials for the development of national defense and the national economy. They are widely used in military, aerospace and sporting goods. , automotive industry, energy equipment, medical equipment, construction machinery, transportation, construction and structural reinforcement and other fields.

▲Carbon fiber is widely used

The global market demand is strong, and high-end demand is growing rapidly. With the increasing demand for carbon fiber in aerospace, sports leisure and industrial applications, the global carbon fiber market has grown rapidly.

In 2008, the global demand for carbon fiber was 36,400 tons, an increase of more than 100% from 2001. In 2011, the global carbon fiber demand reached 4.41 million tons. In 2016, the global demand for carbon fiber was around 65,100 tons.

In the future, as the demand for wind power, automobile industry, aircraft manufacturing, and high-pressure containers grow substantially, as well as the steady development of the sports and leisure industries, the demand for carbon fiber market will grow even more significantly.
