Popis: In this paper, the Taguchi optimization methodology was utilized for optimizing the production parameters of aluminum foam sandwich panels (AFSP) with different skin layers under low-velocity impact loading. The core material of AFSP was A356 aluminum foam reinforced with SiC particles produced by the CaCO3 foaming agent with 20, 30, and 40 mm thicknesses. The skin layers of plates were made of glass/epoxy with the quasi-isotropic and cross-ply layout as well as the pure aluminum layer. The drop weight impact device was used for the impact test. Three types of impactors (spherical, parabolic, and cone) were used. The evaluated impact parameters are the skin layer layout, impactor shape and core thickness of AFSP. Also, the measured response factors were the specific absorbed energy (SAE), maximum displacement (MD), and maximum impact force (MIF). The Taguchi method was used to check the effect of the production parameters on the response factors by creating the orthogonal array (OA). The results indicated that the best combination of production parameters can be determined by the application of the Taguchi method. These results can provide the optimal impact responses (the largest SAE, the smallest MD, and the smallest value of MIF). For the best SAE and MIF, A1–B1–C1 (pure aluminum/conical/20 mm core) was also investigated. Meanwhile, the optimized combination of levels for all the three production factors was examined to provide the lowest MD (A3–B2–C1, cross-ply/parabolic/20 mm core).
