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]
From Petroleum Pitch
Oxidative Stablization
Carbonization
Volatiles
Parallel ring arrangement
Two steps are involved:
Dehydrogenation
Denitrogenation
Graphitization
