One of the solutions is to use composite materials. This research used aromatic polyamide, PE, and honeycomb of different aperture to make plate and investigate the effect of ballistic resistance of the plate. The objective is to achieve the NIJ 0108.01 Ⅲ level standard. This research can be divided into three parts: (1) The optimal analysis: The purpose of this research is to investigate the parameters effect on ballistic resistance of the target. Arrangement of Kevlar and Dyneema, the weight proportion of front and back plates, different aperture of honeycomb are the three parameters considered. Taguchi method was used under considering less experiments and cost. (2) Ballistic testing analysis: We used Kevlar and Dyneema to make the composite panels by heating and pressure, and then glue it to the honeycomb. The panels of different combination based on the fixed area density were executed ballistic testing. Then we analyzed the results and choose the optimal combination by using optimal analysis. (3) Numerical simulation analysis: We used ANSYS/LS-DYNA to model and simulate the process of projectile impacting the target and the results were compared with those from experiments. Keywords：composite materials, optimal analysis, taguchi method.
