Pitch carbon fiber process

Webbwww.researchgate.net Webb19 dec. 2008 · PAN fibers are formed by a process called wet spinning. The dope is immersed in a liquid coagulation bath and extruded through holes in a spinneret made from precious metals. The spinneret holes match the desired filament count of the PAN fiber (e.g., 12,000 holes for 12K carbon fiber).
