Phase-field topology optimization model which aims the maximum rigidity of mechanical structure has been developed and its fundamental performances have been evaluated by performing two-dimensional cantilever simulation. Here, the effects of interface thickness, initial morphology and solid volume fraction on the final morphologies and rigidity have been investigated. As a result, it has been confirmed that the thin interface thickness produces the high rigidity of the structure with small computational cost. Furthermore, the developed model enabled us to maximize the rigidity of mechanical structure stably and easily and the initial morphology dependencies of final morphology were relatively small.
