Investigation of new generation ballistic fabric design and energy absorption in simulative environment according to NIJ 3A standard

In this study, high density polyethylene and ballistic tests according to NIJ 3A standard were analyzed in simulated environment and the results were examined. The biggest disadvantage is that the surface or similar material tests, which are considered to be used in the field of ballistics, are both long in process and high in cost. It is a significant advantage to use real-time and low-error simulation programs instead of performing these tests by preparing individual prototypes or samples. The aim of this study is to save both time and cost. One of the most important parameters for ballistic protective materials is the ability of the surface or material to absorb energy. Therefore, it is aimed to minimize the ballistic effect affecting the body of the person wearing the ballistic material. Within the scope of this study, 450 m / s metal coated shells were sent to the high density polyethylene (HDPE) surfaces, which were designed in Ansys program and whose thickness was between 1 and 8 mm, within the scope of NIJ 3A standard. After completing the ballistic performance tests with the finite element method on the designed surfaces, the analysis results were examined. Thus, the ballistic performance of the new generation high density polyethylene (HDPE) surface modeled and the energy damping ability were revealed.
