Notes:
The microstructure of the polyacrylonitrile (PAN) precursors can strongly affect thestructure of the carbon fibers which determine the final mechanical properties of carbon fibers. Theorientation factors ( n f [removed info] ) of PAN precursors under different draw ratios were characterized by thebirefringence ( [removed info]n f ), which was obtained through polarized microscopy. The results show that theincreasing of the draw ratio may enhance the degree of orientation, which can correspondinglyimprove the mechanical properties. However the increasing speed of the orientation factor slowsdown as the draw ratio reached to 8
