The spun carbon fiber filaments need to undergo carbonization treatment to form high-strength carbon fibers. The carbonization process is usually carried out at high temperatures, causing fibers to decompose into pure carbon in an oxygen deficient environment. The carbonization temperature and time have a significant impact on the quality and properties of carbon fibers. Carbonization is a crucial step in the production of high carbon silk fabric. The control of carbonization temperature, time, and atmosphere has a significant impact on the mechanical properties, structural stability, and thermal stability of carbon fibers. During the carbonization process, inert gases (such as nitrogen, argon, etc.) need to be used as a protective atmosphere to prevent fibers from oxidizing at high temperatures.
