Fabricating carbon composite parts involves a complex series of steps, starting with the base material . Typically, this material is PAN , which is stretched into thin filaments. These filaments are then heated at significant temperatures to improve their fire resistance, followed by carbonization in an oxygen-free atmosphere. This pyrolysis process changes the polymer structure into nearly pure carbon. Subsequently, the resulting carbon strands are often treated with a surface treatment to enhance their sticking to a resin material, typically an polymer resin, during the final component creation. The concluding step includes different methods like fabrication and setting to achieve the desired shape and physical properties.
