Insights into carbon fiber production (Part 2/5)
Carbonization - a model of efficiency and precision
After the oxidation stage, the fibers enter the carbonization stage, where they are processed in special high-temperature furnaces at over 1500°C. The oxidized fibers are refined in a controlled, inert atmosphere - usually nitrogen or argon. These conditions are critical to avoid combustion and prevent unwanted chemical bonding with external elements.
During this phase, the fibers undergo crucial chemical transformations that adapt their microstructure and optimize them for demanding mechanical applications. The yarns are also fed through the furnace in a dense configuration, which not only reduces the footprint but also enables significant energy savings.
Carbonization is thus a prime example of the efficiency and precision with which Teijin refines its products to deliver industry-leading carbon fibers used in aerospace, automotive and many other sectors.
