Recently, the design concepts of sandwich structures have been changed because of the improvements of materials and their manufacturing technology. Fiber-reinforced composites are adopted to make the bilateral faceplates of the sandwich structure instead of using conventional materials, while the honeycombed structures are widely used as the core layer instead of applying solid or other forms of structures. This study concerns with the optimal design of the fiber-reinforced sandwich plate with a honeycombed core with regard to the constraints of the structural buckling strength and the failure strength of the composite sandwich plate under axial compression. The objective is to determine the optimal configuration parameters of the fiber-reinforced sandwich plate with a honeycombed core. The configuration parameters include the thickness of the faceplates, the angle that the laminated fiber is arranged within the faceplate, and the geometric characteristics of the honeycombed core structure, which are including the thickness of the cell wall and the diameter of the cell. Besides, the evaluation will be done with regard to the influence of the parameter design on the fiber-reinforced composite sandwich plate with a honeycombed core.
