Abstract:

The paper presents the results of the depth of penetration tests (DOP) and numerical simulations of the 5.56 x 45 mm SS109 projectile impact onto passive, layered armours placed on the armour backing material. Investigated passive layered armours (with dimensions 100 x 100 mm) were composed of polyester cover; soft ballistic aramid textile layers and Al2O3 ceramic tile placed inside rubberized aramid bag. The 5.56 x 45 mm SS109 projectile was stopped for 7-mm thick ceramic tile. In the final armour modular interlayer will be used and each module will have common area near its edges with neighbouring modules. Considering that for 7-mm thick ceramic tile, the areal density of armour equals 42.1 kg/m2. To decrease the areal density of the modular armour to the value of 20÷30 kg/m2 the numerical simulations with the use of the Ansys Autodyn v15 program were performed as the base for further DOP tests. One and two-layer armours with two kinds of ceramic tiles (Al2O3, SiC), armour steel plate (Armox 500) and titanium plate (Ti6Al4V) were investigated. The results of numerical simulation for the most effective armour for protection against the 5.56 x 45 mm SS109 projectile were presented.
