A Brief Introduction To Carbon Fiber


There are many members of the carbon material family, including macro-scale coke, diamond, expanded graphite,carbon fiberand nanoscale carbon nanotubes, fullerenes and graphene. Among them, coke is mainly used in blast furnace ironmaking, mechanical casting, calcium carbide production, chemical fertilizer chemical gas production, etc. The real materials used for material preparation are expanded graphite, carbon fiber and various nano-carbon materials. These carbon materials either become part of composite materials as fillers, or themselves become a series of products that can be seen everywhere in production and life, such as sealing materials and building materials, through processes such as weaving and molding.
 
 
Carbon fiber is a fibrous carbon material that is lighter than aluminum, stronger than steel, thinner than human hair, and contains more than 90% carbon. It has excellent properties such as high impact strength, high tensile modulus, low density, high temperature resistance, ablation resistance, corrosion resistance, high electrical and thermal conductivity, low thermal expansion, self-lubrication and good biocompatibility. Most carbon fibers are composed of incomplete graphite crystals arranged along the fiber axis. They are hexagonal network layered accumulations composed of sp^2 hybridization. The crystallites composed of carbon atoms are the microstructural units of carbon fibers. The layer spacing is about 0.3360~0.3440mm, and the parallel layers are irregularly stacked, lacking three-dimensional orderly arrangement, and showing a turbulent layer structure. When carbon fiber is annealed at high temperature, it experiences a high temperature above 2500°C. When the carbon content is greater than 99%, the interlayer spacing decreases, indicating that the carbon atoms have transformed from the turbostratic structure to the three-dimensional ordered graphite structure, forming a graphite-like structure. These two types of fibers are divided into carbon fibers and graphite fibers in China and the United States according to different heat treatment temperatures, while in Japan and Europe, they are used to be collectively referred to as carbon fibers.
 
After carbon fiber was invented to replace filament in the early 18th century, it is widely used in textiles, materials, military, aerospace, atomic energy and other fields. Since carbon fiber began to develop on a large scale with technology, its output has grown at an average rate of more than 15% every year. By 1990, the world’s total carbon fiber production was 10,496t. In order to meet the needs of general industrial carbon fiber, its industry turned to large The tow direction is developed and the production scale is expanded from a hundred tons to a thousand tons.
