Production Processes of Carbon Fiber Manufacturers

The production processes of carbon fiber manufacturers are complex and refined, involving multiple stages, each critical to the quality and performance of the final product.

Raw Material Processing

The primary raw materials for carbon fiber include polyacrylonitrile (PAN) fibers and pitch-based fibers. First, these raw materials undergo pretreatment to ensure their purity and uniformity.

Spinning

The pretreated raw materials are processed into filaments through a spinning mechanism. This process requires strict control of temperature, pressure, and speed to ensure the uniformity and strength of the fibers.

Oxidation Stabilization

The filaments are heated in air for oxidation, stabilizing their structure and preventing melting during the subsequent carbonization process. The oxidation typically occurs at temperatures between 200 and 300 degrees Celsius.

Carbonization

The oxidized filaments are heated to temperatures ranging from 1000 to 3000 degrees Celsius in an inert gas environment to remove non-carbon elements, forming pure carbon fibers. The carbonization process determines the final strength and modulus of the carbon fibers.

Surface Treatment

The carbonized fibers require surface treatment to enhance their bonding strength with matrix materials. Surface treatment methods include electrochemical treatment and chemical coating.

Composite Material Molding

The treated carbon fibers are combined with resin, metal, or ceramic matrices, and shaped into various forms and properties using processes such as compression molding, pultrusion, and winding.
