What is the primary source material used for creating pitch-based carbon fibers?
Answer
Byproducts of petroleum refining or coal tar distillation
Pitch-based carbon fibers are produced using pitch, which is a viscous substance derived from petroleum refining or the distillation of coal tar. This precursor pathway is distinct from PAN-based production and is primarily utilized to create fibers that exhibit excellent stiffness characteristics, though they may have different tensile strength profiles compared to their PAN counterparts.
