PAN계 탄소섬유의 제조 및 탄화 조건에 따른 특성 분석 = Preparation and Characterization of PAN-based Carbon Fiber with Carbonization Temperature

다국어 초록 (Multilingual Abstract)

In this study, PAN (polyacrylonitrile)-based carbon fiber was prepared under different carbonization conditions. Carbonization of oxi-PAN fiber was performed under four different temperature conditions. Changes in the characteristics of these carbon fibers prepared 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. Thermal characteristics were analyzed using a thermogravimetric analyzer (TGA). The result showed that the crystal size and crystallinity of the carbon fibers increased with carbonization temperature. Furthermore, both mechanical strength and thermal resistance were also observed to improve with carbonization temperature. Finally, a relationship between carbonization temperature, thermal properties, and mechanical properties of the carbon fibers was derived.
