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.

The present cost for low carbon steel coil is $1.10/kg [7] and the average cost of recycled aluminum in 2024 was $2.27/kg [8]. Figure 1 demonstrates these differences in cost. Figure 1: Aluminum and Steel cost/kg compared to carbon fiber cost/kg.
WebTypically, either pitch or rayon fibers are used in these applications; however these fibers are foreign-sourced and are relatively high cost. Pitch fibers in particular have unstable pricing due to swings in petroleum price. Lignin-based carbon fibers (LBCF) could have been a direct substitute for pitch or rayon fibers within these applications. WebDec 6, 2012 · In this work, two rayon fibers were investigated as carbon fiber precursors. A detailed consideration has been applied to a domestically produced cellulose fiber to carbon fiber (CF) transition. This transition of precursor to carbon fiber can be subdivided into two stages: pyrolysis (thermal decomposition) of cellulose in air and high temperature …
