Manufacturing carbon reinforced parts involves a intricate series of steps, beginning with the base material . Typically, this precursor is polyacrylonitrile (PAN) , which is stretched into small filaments. These fibers are then heated at high temperatures to improve their heat resistance, followed by graphitization in an oxygen-free atmosphere. This pyrolysis process transforms the polymer structure into nearly pure carbon. Subsequently, the resulting carbon filaments are often treated with a surface treatment to enhance their bonding to a resin material, typically an plastic resin, during the final part creation. The concluding step includes various methods like layup and curing to achieve the specific form and structural properties.
