Production of Polyacrylonitrile (PAN) Precursor for

Polyacrylonitrile (PAN) is the predominant precursor for carbon fiber due to a superior strength and stability, and higher carbon yield. About 90 % of the carbon fiber produced is made from PAN and the remaining 10 % is made from rayon or petroleum pitch. The first step in the production of PAN-based carbon fibers is spinning the PAN co-polymer
