Fabricating carbon composite parts involves Carbon Fiber Processing a complex series of steps, commencing with the base material . Typically, this precursor is polyacrylonitrile (PAN) , which is extruded into fine filaments. These filaments are then oxidized at elevated temperatures to improve their thermal resistance, followed by pyrolysis in an oxygen-free atmosphere. This graphitization process transforms the plastic structure into nearly pure carbon. Subsequently, the resulting carbon strands are often coated with a bonding agent to boost their bonding to a resin material, typically an epoxy resin, during the final product creation. The concluding step includes different methods like molding and hardening to achieve the specific shape and mechanical properties.
