  Abstract

In this work, plasticized spinning PAN fibers were treated at low carbonization temperature for the first time. The properties of treated fibers were characterized by elemental analysis (EA), scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR) respectively. The SEM results show that cross section of the pre-carbonized fibers is circular with no apparent skin-core structure. During the pre-carbonization process (320-380 ), fracture mode of the fibers gradually changes from ductile to brittle and fibril diameter gradually decreases. Pre-carbonization temperature at 350 significantly accelerates chemical reactions. The FTIR results show that a stable oxygen structure is generated as treated at 320 .
