Partial carbonization of aramid fibers

Journal of Polymer Science Part B: Polymer Physics, 1994
AbstractHeat treatment of aramid fiber was conducted in the temperature range 300–710°C nominally for 10 and 30 s in both static air and flowing nitrogen atmosphere. Crystallinity, crystal orientation, and crystallite size were determined using x‐ray diffraction.
