ABSTRACT: A Kraft hardwood lignin (HWL) and an organic-purified hardwood lignin (HWL-OP) were evaluated as potential precursors for the production of lowcost carbon fibers. It was found that the unpurified HWL exhibited poor spinnability while the HWL-OP exhibited excellent spinnability characteristics. Fibers of various diameters were obtained from the HWL-OP. Thermostabilization studies showed that oxidative stabilization can only be used to convert HWL-OP-based fibers into carbon fibers if extremely low heating rates are applied. Carbonized lignin-based fibers had tensile strength of 0.51 GPa and tensile modulus of 28.6 GPa. VC
