Porous carbon materials have been expected as heat protection materials, fuel cells, and space craft structures. In this study, a porous carbon material having a monolith structure was prepared using a spinodal decomposition mechanism. Compression testing and image-based modeling using tomography were also carried out, and elastic properties of carbon monoliths were examined experimentally and analytically. The created models reflected the microstructure of porous carbon very well. By homogenization and simulating the compression test, stress distribution occurring generating in the model was predicted. Maximum shear stress in struts corresponded to that of bulk glassy carbon at the time of the compression failure. Therefore, it was indicated that a fracture of carbon monolith occured when a maximum shear stress in strut reached that of a solid material.
