Carbon fiber is an important material in the emerging industrial system. Carbon fiber is currently used as a raw material in many high-end industrial products. Because this material was originally used in confidential industries such as military industry and aerospace, and foreign countries have banned sales in China, it is still relatively mysterious to most people, and there are many misunderstandings about carbon fiber.
Carbon actually does not refer to a certain material but a material system with carbon as the main component. Generally, materials with higher carbon content are collectively called carbon materials, including graphite, carbon, diamond, carbon fiber, etc. are included in this material classification.
Carbon fiber is a reinforced fiber material with a carbon content of more than 95% prepared at high temperature. It is a stack of graphite in the form of fibers. The way to industrially produce this material is to use three fiber materials: asphalt, viscose, and polyacrylonitrile. , currently most raw fiber manufacturers use polyacrylonitrile to prepare carbon fiber filaments. Carbon fiber has strong tensile strength, is very light, and has stable composition. It is often used as a reinforcing material in combination with other materials and has better performance than ordinary materials.
Through the meanings represented by the two, we can see that the difference between carbon and carbon fiber is that carbon fiber belongs to a subcategory of carbon materials, and carbon materials are a large category with carbon as the main component.
There is another material called carbon fiber. In fact, carbon fiber refers to carbon fiber prepared from polyacrylonitrile. At present, carbon fiber is actually carbon fiber, but it is only in the name and specifically refers to a certain type of carbon fiber. the difference.
