The work concerns the analysis of a material solution on an aramid laminate reinforced with additional composite layers loaded with ballistic impact from the 7.62 mm M43 Full Metal Jacket (FMJ). The aim of the study is to identify alternative material systems to the reference 4 mm thick Armox A500T armored steel solution. The research was carried out using the finite element method with the application of the ABAQUS program. The optimal solutions for individual material systems were generated based on numerical analyses, thereby classifying them according to the mass-efficiency criterion. The numerical results obtained were validated in a ballistic experiment on samples made according to the methodology adopted for modeling. The range of absorbed energy and residual energy was determined for material systems based on the assumptions of the Recht-Ipson model.
