Abstract
In this study, I propose to improve the material features such as heat dissipation and water absorption by using a fractal on material structure for the purpose of surface area expansion. The usefulness of the fractal structure having a self-similar in part and whole was revealed in conjunction with the analysis. In the analysis, the improvement of the water absorption and heat transfer in the fractal could be expected. Unfavorable shape to simple diffusion as linear square fractal was present in the test specimen experiment. In addition to that, the results show that heat transfer inhibition caused by the formation of the boundary layer by convection in the triangular fractal. Therefore, selection of the optimal fractal structure according to the various purpose is required.
