Manufacturing carbon composite parts involves a intricate series of steps, commencing with the precursor. Typically, this substance is polyacrylonitrile (PAN) , which is drawn into small filaments. These filaments are then heated at significant temperatures to improve their thermal resistance, followed by pyrolysis in an non-reactive atmosphere. This graphitization process transforms the resin structure into nearly pure carbon. Subsequently, the resulting carbon filaments are often sized with here a coupling agent to enhance their sticking to a resin material, typically an epoxy resin, during the final product creation. The final step includes various methods like molding and hardening to achieve the required shape and mechanical properties.
