Abstract:   (6006 Views)
Shaped charges defeat armours by means of high velocity jets formed by the collapse of a metallic liner as a result of the detonation of an explosive. The explosive formulation is an important factor influencing the properties of a shaped charge. Explosive charges used in penetrating devices have usually high detonation velocity and high density. In this research, composition based on HTPB having different amount of aluminum (0 up to 40 percent by weight) was examined in a specific shape charge. Total weight of explosive was about 30 g. Shaped charges of 40 mm calibers were prepared and penetration experiments were carried out at 25 mm stand-off distance on mild steel targets. The results established high penetration capability of aluminum-free formulation. Penetration resulted by this charge has a 61 mm depth and 4.4 cm3 volume. There is a nonlinear decrease in the penetration of the shaped charges by adding aluminum in formulation of explosives.
