Abstract
A new technique for treating non-PAN-based pre-cursor polymeric fibers, tows, yarns, and films has been created for use in making stabilized pre-cursor polymers. By applying stepwise or non-stepwise microwave and/or ultraviolet radiation to the pre-cursor polymeric fibers, tows, yarn, or films prior to the stabilization thereof, a reduction in time for the costly stabilization process is achieved. Application of this technique extends to less-costly production of carbon fibers, for uses in industries such as automotive, aviation, trains, medical, military, sporting goods, orthopedics, and other industries. The pre-cursor polymeric fibers, tows, yarns, or films may be a multi-component polymer composite comprised of a non-PAN-based polymeric fiber, tow, yarn, or film and at least one or more constituent materials. Carbonization of such pre-cursor polymeric fibers, tows, yarns, or films results in less-costly carbon fibers that perform equally, if not better, than traditional costly PAN-based carbon fibers.
