3. 2. Evaluation of the Carbonization of Thermo-Stabilized Lignin Fibers into Carbon Fibers

   University essay from Linköpings universitet/Kemi; Linköpings universitet/Tekniska fakulteten

   Author : Henrik Kleinhans; [2015]
   Keywords : Lignin; Carbon Fibers; Carbonization; Stabilization; Uniaxial Tensile Testing; Thermomechanical Analysis TMA ; Thermogravimetric Analysis TGA ; Fourier Transform Infrared Spectroscopy FTIR ; Scanning Electron Microscope SEM ; Energy Dispersive X-ray Spectrometer EDS ;

   Abstract : Thermo-stabilized lignin fibers from pH-fractionated softwood kraft lignin were carbonized to various temperatures during thermomechanical analysis (TMA) under static and increasing load and different rates of heating. The aim was to optimize the carbonization process to obtain suitable carbon fiber material with good mechanical strength potential (high tensile strength and high E-modulus). READ MORE
