WebMay 1, 2002 · Similar TGA curves show the same pyrolysis mechanism, and based on this, lyocell fibers are proposed as high performance carbon fiber precursors. Lyocell fibers are successfully carbonized under conditions identical to those for manufacturing rayon-based carbon fibers. The two kinds of carbon fibers are compared by SEM and a Weibull … WebCommercially available carbon fibers are based on one of three precursor materials -- rayon, PAN (polyacrylonitrile) and pitch. Early research in each of these carbon fiber types dates back to the late 1950s. Rayon, converted into a carbon fiber, was found to deliver the strongest and stiffest material for its weight that had ever been produced.
