NUMERICAL SIMULATION OF THE CARBONIZATION PROCESS IN THE MANUFACTURING OF CARBON-CARBON COMPOSITES

탄소-탄소 복합재료의 제조 과정 중 탄화과정의 수치 해석에 관한 연구

A method for numerical simulation of the carbonization process in manufacturing of a carbon-carbon composite is developed. A general theory, which consists of analyses of heat and mass transfer together with stress and displacement predictions, is constructed. A homogeneous, single phase, isotropic material is selected and a computer program is developed for an arbitrary 2-dimensional geometry using FEM. Material properties are obtained through experiments and references, and are modeled effectively to serve the simulation purpose. The validity of the simulation is verified through several comparisons with experimental data, where close agreements are observed. Finally, examples of actual applications are considered to exhibit the capability and utilization of the code in process optimization.
