重合誘起相分離法により構造を形成させた多孔質炭素材料の力学特性評価

It is well known that the mechanical behavior of porous materials strongly depends on porosity and pore morphology. On the other hand, their complex shape and structure make the reproduction of deformation and failure by simulation difficult. In such a case, analyses using model reflecting the complex structure of porous material (image based modeling) are quite effective. Although model of porous carbon obtained by using FIB-SEM and X-ray CT have been conducted and material properties have been evaluated,(1) the relationship between geometric structure and mechanical properties has not yet been generalized. Therefore, the objective of this study is to evaluate the relationship between geometry and mechanical properties of carbon monolith, which is a porous material with controllable geometric factors and mechanical properties. Strut length, thickness and the joint diameter of struts are selected as geometric factors and image based modeling is conducted for reconstruction model obtained by X-ray CT. Design guidelines for mechanical properties of porous materials will be discussed in the presentation.
