Abstract The present work proposed a type of layered aluminum honeycomb sandwich structure from the perspective of sacrificial cladding designing. By drop weight impact test, the responses of the specimens with different combinations were obtained under two energy level impact. By comparing the energy absorption, peak value of impact load, displacement of impactor, deflection of specimens, some conclusions were drawn as follows: there was permanent plastic deformation accompanied by a certain degree of elasticity deformation in the structures under lower energy level (17—83 J) impact. On the premise of the same quality, the honeycomb with smaller size and smaller height should be given priority as the core of the sandwich structures. The critical value should be between 83—119 J. In the design of sacrificial cladding, the limit energy design value of local impact should be lower than the critical value; the relative density of core layer significantly influences the local impact resistance of the structure; according to the design criterion of sacrificial cladding, within the research scope of this paper, type AB, BA and ABA structures have comparative advantage according to the aggregative indicators. The results provide helpful reference for practical application of the layered aluminum honeycomb sandwich structure in protective engineering.
