Carbon fibers are manufactured from one of the three major precursors, i.e., polyacrylonitrile, pitch or rayon. in our earlier research, it was shown that carbon fibers with good yield can be produced from polyethylene precursors. due to the thermoplastic nature of the precursor, the stabilization was achieved by crosslinking using sulfuric acid. this dissimilar method of stabilization as well as the different structure of the stabilized fiber is likely to ...
In this research, an effort is made to produce carbon fibers from a highly ordered and oriented polyethylene fiber. Sulfonation of the fiber is studied as a method of stabilizing this thermoplastic fiber for higher temperatures of carbonization. The effect of time, temperature, tension and medium of sulfonation is being studied systematically. The progress of reactions and the extent of stabilization is studied by thermal analyses (Differential Scanning Calorimetry and ...
