C/SiC 복합재의 기계적 특성에 미치는 초기 기공의 영향

Effect of Initial Porosity on Mechanical Properties in C/SiC Composite

Four kinds of raw C/C composites with a density between 1.2S-1.66g/cm² were used in order to investigate the effect of the initial porosity of C/C composites on mechanical properties of liquid silicon infiltrated C/SiC composites. The microstructure observation, image analysis and flexural strength test of the composites were performed. The density and microstructural changes with the variation of the initial porosity was discussed in the terms of the infiltration behavior of liquid silicon.
