Abstract
A method of fabricating carbon fibers includes the steps of: (a) melting asphaltene solids in a sealed vessel; (b) spinning melted asphaltenes to fabricate green fibers; (c) stabilizing the green fibers; (d) carbonizing the stabilized green fibers; and (e) optionally graphitizing carbonized fibers.
