 Based on method of production
Based On Carbon Content
Based On Method Of Production
Production Of Carbon Fibre
STEPS INVOLVED:-
 Oxidative stabilization [200-300⁰C]
 Carbonization (non-oxidative) [1000-1500⁰C]
 Graphitization (non-oxidative) [1500-2500⁰C]

 Parallel ring arrangement
Two steps are involved:
 Dehydrogenation
 Denitrogenation
