PAN based carbon fiber precursors use accelerated E-beam stabilization of PAN based carbon precursor fibers to make carbon fiber. Compositions are also proposed for melt-assisted spinning of high acrylonitrile content precursors.
Other melt-spin technology allows for ultra-high strength carbon fibers. Current carbon fibers dominate the market for advanced structural fibers because of their superior strength/weight properties; however, this invention addressing synthesis, purification, doping and specialty processing can produce a two-fold increase in strength.
Various grades of PAN based precursors have been developed, requiring various new compositions for melt-spun PAN (as well as solution spun PAN) fibers. Using ORNL methods, carbon fiber can be made less expensively.Also, in our search for low-cost carbon fiber, we developed a method to create ultra-high strength structural carbon fiber, which can be licensed independently for those interested in pursuing those applications. Additional research incrementally bridges the gap between the two, and never ceases to
