摘要： A method of making a carbon fiber includes heat treating a lignin precursor absent an active ingredient in an inert atmosphere to raise the glass transition temperature (Tg) of the precursor by at least five (5%) percent, forming a lignin precursor having an increased Tg (High Tg Lignin). The High Tg Lignin can be spun into a fiber. The fiber may then be stabilized to form a thermoset fiber. The time period for stabilizing the fiber is less than one hundred (100) hours.
