In this study, PAN (polyacrylonitrile)-based carbon fiber was prepared under dif- ferent carbonization conditions. Carbonization of oxi-PAN fiber was performed under four different temperature conditions. Changes in the characteristics of these carbon fibers pre- pared under each condition were studied using various analyses. Crystalline characteristics of carbon fiber such as crystallinity and crystal size were analyzed using X-ray diffraction (XRD) and Scherrer's equation, based on the XRD patterns, respectively. The tensile strength and modulus of these carbon fibers were measured through a tensile test. Ther- mal characteristics were analyzed using a thermogravimetric analyzer (TGA). The result showed that the crystal size and crystallinity of the carbon fibers increased with carboniza- tion temperature. Furthermore, both mechanical strength and thermal resistance were also observed to improve with carbonization temperature. Finally, a relationship between car- bonization temperature, thermal properties, and mechanical properties of the carbon fibers was derived.
