Chopped Carbon Fiber Manufacturing Process

The manufacturing of chopped carbon fiber involves several steps that should be executed precisely to yield high-quality fibers. These steps include:

1. Polymerization: This is the first stage of the process, where a high-quality precursor fiber, usually PAN, is formed, and then polymerized at high temperatures to yield the carbon fiber.
2. Stabilization: The second stage of the process involves stabilizing the precursor fiber further by heating it at a precise temperature in an oxygen-free environment. The stabilization process prevents the fiber from shrinking during the carbonization process.
3. Carbonization: The third stage of the process is carbonization, where the stabilized precursor fiber is heated up to temperatures above 1000°C, causing it to lose its non-carbon atoms and transform into carbon fiber. The carbonized fiber is then oxidized to get rid of any residual impurities, creating a pure carbon fiber.
4. Chopping: Once the manufacturing process of carbon fiber is complete, it is then cut into small pieces using a mechanical chopper. The length of the chopped fiber strands depends on the intended application.

Several manufacturers specialize in the production of high-quality chopped carbon fiber. The market offers various grades of chopped carbon fiber, so it is essential to select the right manufacturer to ensure top-quality products.
