Carbon fiber popular science:

Introduction to carbon fiber products:

 Due to the extremely high material properties of carbon fiber, carbon fiber products have high strength and high hardness, far exceeding the same weight and weight of metal materials. Therefore, carbon fiber products have a wide range of applications in high-tech industries such as aviation, navigation, and military. 

  Material properties of carbon fiber:

 1. The weight of carbon fiber is equal to one quarter of the same volume of steel.

2. The strength of carbon fiber products is ten times that of the same volume of aluminum.

There is also a previous statement that carbon fiber products have a strength equal to that of metal strength compared to metal materials of the same quality.

Introduction to carbon fiber raw materials: 

Carbon fibre, as its name suggests, is not only the inherent intrinsic property of carbon materials, but also the soft processability of textile fibers. It is a new generation of reinforcing fibers. Compared with traditional glass fiber (GF), Young's modulus is more than three times; compared with Kevlar fiber (KF-49), not only the Young's modulus is about 2 times, but also in organic solvents. Insoluble in acid and alkali, the corrosion resistance is outstanding. Some scholars immersed PAN-based CF in a strong alkaline NaOH solution in 1981. It has been more than 20 years since it has maintained its fiber shape.

      Carbon fiber can be obtained by carbonization of polyacrylonitrile fiber, asphalt fiber, viscose fiber or phenolic fiber respectively; it is divided into filament, short fiber and chopped fiber according to state; it is divided into general type and high performance type according to mechanical properties. The general-purpose carbon fiber has a strength of 1000 MPa and a modulus of about 100 GPa. The high-performance carbon fiber is further classified into a high-strength type (strength 2000 MPa, modulus 250 GPa) and a high model (modulus 300 GPa or more). The strength is greater than 4000 MPa, also known as ultra-high strength; the modulus is greater than 450 GPa, called the ultra-high model. With the development of the aerospace and aviation industries, high-strength and high-stretch carbon fibers have emerged with an elongation of more than 2%. The largest amount is polyacrylonitrile PAN-based carbon fiber.

The carbon fibers currently used more commonly are polyacrylonitrile carbon fiber and asphalt carbon fiber. The production of carbon fiber includes four processes of fiber spinning, heat stabilization (pre-oxidation), carbonization, and graphitization. The accompanying chemical changes include dehydrogenation, cyclization, oxidation, and deoxidation.

    Carbon fiber is a new material for military and civilian use and is a key material for technology-intensive and politically sensitive. In the past, the United States-led Paris Coordinating Committee (COCOM) imposed an embargo blockade policy on the socialist countries at that time. In March 1994, although COCOM had been dissolved, the shadow of the embargo blockade still hangs over the sky, advanced carbon fiber technology. Still can not be introduced, especially the high-performance PAN-based raw silk technology, even if China enters the WTO, the situation will not change greatly. Therefore, there is no other choice than the Chinese people continue to develop their own carbon fiber industry. Therefore, countries such as Japan and South Korea, which are leading in carbon fiber production technology abroad, have always been very cautious about the export of carbon fiber materials and products in China. Only a small number of Chinese companies can establish cooperative relations with them and have import channels for their products.

     Although China's carbon fiber production is developing slowly, consumption has been gradually increasing, and market demand is strong. The main uses include sports equipment, general industry and aerospace, among which sports and leisure products are the most used, accounting for about 80% to 90% of consumption. China's carbon fiber demand has exceeded 3,000 tons / year, and will exceed 5,000 tons / year in 2010. The main application areas are: mature markets include aerospace and defense (aircraft, rockets, missiles, satellites, radars, etc.) and sports and leisure products (golf clubs, fishing gear, tennis rackets, badminton rackets, arrow rods, bicycles, rowing boats, etc.) Emerging markets include reinforced plastics, pressure vessels, building reinforcement, wind power, friction materials, drilling platforms, etc.; the market to be developed includes automobiles, medical devices, and new energy sources.
