Carbon fiber is a kind of inorganic high-performance fiber with more than 90% carbon content, which is transformed by a series of heat treatment. Carbon fiber is a new material with excellent mechanical properties. It has the inherent characteristics of carbon materials, and also has the soft and processable textile fiber. It is a new generation of reinforcing fiber.
From a professional standpoint, it should be called carbon fiber, and carbon is different from carbon only. At present, carbon fiber is generally not used alone, and can be combined with other materials, such as glass fiber reinforced plastic, carbon carbon composite materials, carbon fiber plays a role in strengthening and toughening.
It belongs to the subject of composite materials under material science and engineering. Carbon fiber is a kind of polymer material, which has the highest strength in the field of materials at present. The strength of carbon fiber is more than 4900 MPa, which is more than 10 times the strength of ordinary steel.
