Producing carbon reinforced parts involves a intricate series of steps, commencing with the base material . Typically, this substance is polyacrylonitrile (PAN) , which is drawn into fine filaments. These fibers are then heated at high temperatures to improve their heat resistance, followed by graphitization in an non-reactive atmosphere. This graphitization process transforms the polymer structure into nearly pure carbon. Subsequently, the resulting carbon filaments are often treated with a bonding agent to boost their adhesion to a composite material, typically an plastic resin, during the final part creation. The final step includes different methods like molding and curing to achieve the required shape and mechanical properties.
