Carbon Fiber

Carbon fiber


Carbon fiber is made of polyacrylonitrile and other organic parent fiber, in high temperature environment cracking carbonization formed carbon main chain mechanism, carbon content in more than 90% of the high strength and high modulus fiber, with high temperature resistance, friction resistance, electricity, heat conduction and corrosion resistance and other characteristics. Is made of acrylic fiber and viscose fiber as raw materials, oxidized and carbonized by high temperature. It is also a good material for manufacturing high-tech equipment such as aerospace, but is often called "black gold" because of its high price.


1:Industrial chain

The carbon fiber industry chain consists of crude oil chemical industry in the upstream, raw silk processing in the middle, carbon fiber related products and carbon fiber composite production and processing, core machinery manufacturing and downstream application market.


2: The upstream analysis

Carbon fiber upstream belongs to the petrochemical industry, first from petroleum, coal, natural gas and other fossil fuels to prepare propylene, and through ammonia oxidation to get acrylonitrile; Acrylonitrile is polymerized and spun to produce polyacrylonitrile (PAN) profilaments. Carbon fiber enterprises generate polyacrylonitrile by polymerization of acrylonitrile - based raw materials, and then spinning to obtain polyacrylonitrile filament.


Carbon fiber industry technical barrier is high, carbonization oxidation is the key. Propane can be prepared from crude oil and propylene can be obtained by selective catalytic dehydrogenation (PDH).


Compared with the other two kinds of carbon fiber, polyacrylonitrile is less difficult to process, and has excellent product quality and excellent mechanical properties, is the mainstream of carbon fiber.



3: Market Size


Carbon fiber is composed of polyacrylonitrile and other organic parent fiber, which is decomposed and carbonized to form carbon main chain mechanism under high temperature environment. It is a high-strength and high-modulus fiber with more than 90% carbon content. It has the characteristics of high temperature resistance, friction resistance, electric conduction, heat conduction and corrosion resistance. According to the data, China's carbon fiber production capacity and output will reach 36,200 tons and 18,500 tons respectively in 2020, and is expected to reach 44,300 tons and 27,700 tons respectively in 2022.
