N2 - This article described a two-step structure layout grow method for a cellular reinforced hybrid sandwich structures design with CFRP face sheets. In the first step a ground structure method is applied to get the initial structure topology data and a homogenize operation is taken to distribute the material to the base mesh grid centroid. In the second step, a bionic graph-based topology method which like the cell division is present to make the layout automatically grow. And for the optimization process, an evolution method of genetic algorithm is used to get the optimize result from the varied feasible solutions. A comparison between the pure honeycomb core sandwich and ortho-grid core honeycomb sandwich are taken which reflect a high performance by our method in the gird stiffener topology design.
