Carbon fiber is a kind of high-strength and high modulus fiber with more than 90% carbon content, which has high strength, small specific gravity, high temperature resistance, friction resistance, corrosion resistance and other characteristics. It is mainly composed of carbon element, with fiber shape, soft and can be processed into various fabrics. The proportion of carbon fiber is less than 1/4 of steel, but its strength is 7-9 times of steel. 1
Carbon fiber is formed by pyrolysis and carbonization of organic fibers such as polyacrylonitrile (PAN), asphalt or viscose under high temperature environment. According to the type of precursor, carbon fiber can be divided into three categories: polyacrylonitrile (PAN) based carbon fiber, pitch based carbon fiber and viscose based carbon fiber. Among them, PAN based carbon fiber is one of the most widely used and the largest output due to its low process difficulty and excellent product quality and mechanical properties.
Carbon fiber has a wide range of applications, including aerospace, rail transit, ship vehicles, new energy and other fields. For example, carbon fiber is used to manufacture aircraft, launch vehicles, wind turbine blades, sports goods such as tennis rackets and bicycles. In addition, carbon fiber is also used to manufacture high-performance composites, further expanding its application field. Now, the development prospect of carbon fiber in the textile industry is discussed.
The development of carbon fiber in the textile industry is mainly reflected in the following aspects:
1. Application of high-performance fiber materials: As an important inorganic high-performance fiber, carbon fiber has been rapidly developed and applied in the textile industry due to its excellent mechanical properties and soft processability of textile fibers. It is used to strengthen resin materials and form carbon fiber reinforced resin (CFRP), which has practical and potential applications in many fields.
2. Lightweight and efficiency improvement of textile machinery: carbon fiber materials are used in textile machinery parts to reduce energy consumption and improve production efficiency due to their lightweight and high-strength characteristics. For example, the use of carbon fiber shuttle and arrow shaft not only reduces the weight, but also improves the shuttle frequency and service life.
3. Application expansion of industrial textiles: the application of carbon fiber in industrial textiles, especially in the lightweight of transportation tools, has promoted the iterative upgrading of carbon fiber application technology. In addition, carbon fiber is also used to make new energy equipment components such as wind turbine blade girder and carbon carbon composite crucible for photovoltaic, which promotes the realization of the goal of "double carbon".
4. Technological innovation and product research and development: The textile industry is improving the added value and market competitiveness of products through technological innovation, such as the research and development of carbon fiber composites. Policies also encourage enterprises to accelerate R&D and innovation around new fiber materials, functional textiles, intelligent manufacturing equipment and other fields.
5. Green and low-carbon development: the use of carbon fiber materials contributes to energy conservation and emission reduction. For example, in the application of maglev train body materials, the use of carbon fiber composite materials has reduced the weight by 30%, increased passenger capacity by 20%, reduced operating energy consumption, and made it more energy-saving and environmentally friendly.
6. Policy support and industrial agglomeration: national policies continue to promote the healthy and orderly development of carbon fiber, and plan to form large carbon fiber enterprise groups and industrial clusters with international competitiveness. The local government has also introduced relevant policies to support the development of carbon fiber industry.
7. Market size and capacity growth: With the progress of carbon fiber technology and the reduction of cost, the market demand continues to grow, and China has become the world's largest carbon fiber production country.
