Effects of Ultra-high Temperature Treatment on the Microstructure of Carbon Fibers
The microcrystalline structure and microvoid structure in carbon fibers during graphitization process (2300-2700 ℃) were characterized employing laser micro-Raman scattering (Raman)
X-ray diffraction (XRD)
small angle X-ray scattering (SAXS)
and high-resolution transmission electron microscopy (HR-TEM). The crystalline sizes (
L

L
c
) increased and interlayer spacing (
d
002
) decreased with increasing heat treatment temperature (HTT). The microvoids in the fibers grew up and contacted to the neighbors with the development of microcrystalline. In addition
the preferred orientation of graphite crystallite along fiber axis decreased and microvoids increased. The results are crucial for analyzing the evolution of microstructure of carbon fibers in the process of heat treatment and important for the preparation of high strength and high modulus carbon fibers.
