الوصف: A composite double-layer honeycomb sandwich structure is proposed to improve the impact resistance of fillers in helicopter rotors, 44 groups of those structures are numerically simulated by LS-DYNA finite element analysis software. An approximate expression for fracture energy of the composite structure is derived. The cell diameter, its wall thickness, and material strength are related to the impact resistance of the structure. With a decrease in the cell diameter and an increase in its wall thickness and material strength, the energy absorption rate of the composite structure is gradually enhanced. Among the 44 composite groups, the structure with the cell diameter of D = 3 mm, the wall thickness of 0.08 mm, and 4340 steel possessed the best energy absorption effect, the energy absorption rate is 54.7% more than for the cell diameter of D = 6 mm and 2024 aluminum. The honeycomb structure composed of various cell diameters has little difference, but it exerts a certain effect on the cell diameter.
