The Significance Of The Emergence Of Carbon Fiber

Carbon fiber is made of acrylic fiber and viscose fiber after high temperature oxidation and carbonization. Due to the preferred orientation of graphite microcrystalline structure along the fiber axis, carbon fiber has a high modulus and strength. Carbon fiber has the characteristics of high temperature resistance, friction resistance and electrical conductivity due to the high quality of carbon element, but it is soft in texture and can be woven and processed. It is generally combined with resin, metal, ceramic and other materials to form a carbon fiber composite material, in which carbon fiber reinforced epoxy Resin composite materials are the most widely used carbon fiber composite materials.

As early as 1879, Edison had made carbon fiber, but the carbon fiber mechanical capacity at that time was very low, so industrial production was not achieved. By the middle and late 20th century, after improving the production process of carbon fiber in the United States, Japan and other countries, it has produced high-strength, ultra-high-strength, high modulus and other high-performance carbon fiber products. The tensile strength of carbon fiber can reach 5.5GPa, making carbon fiber Application development has entered a high level.
The raw materials used in industrial carbon fiber manufacturing include: viscose fiber, polyacrylonitrile fiber and asphalt fiber. After stabilization, carbonization, and graphitization, high-performance carbon fiber materials are produced.
The high temperature resistance of carbon fiber ranks first among all chemical fibers, and it has light weight, heat resistance, and corrosion resistance. After being compounded with various reinforcing materials, it can be widely used, and can be widely used in rockets, aircraft, aerospace, drone shells, automotive material, Oil extraction and other fields.

The development of carbon fiber materials means the development and progress of science and technology, making many impossible possible, and is an indispensable new material in the new era.
