Manufacturing carbon composite parts involves a complex series of steps, beginning with the base material . Typically, this precursor is PAN , which is stretched into thin filaments. These fibers are then oxidized at significant temperatures to improve their heat resistance, followed by graphitization in an inert atmosphere. This graphitization process changes the plastic structure into nearly pure carbon. Subsequently, the resulting carbon strands are often sized with a coupling agent to improve their adhesion to a composite material, typically an polymer resin, during the final part creation. The ultimate step includes multiple methods like molding and setting to achieve the specific geometry and mechanical properties.
