Armox500, okrętowego stopu aluminium i stali kadłubowej. Stal Armox500 jest stosowana na osłony balistyczne dla środków transportu bojowego (lądowego w gatunku T i morskiego w gatunku S). W tym celu przeprowadzono przestrzeliwanie tych materiałów pociskiem kalibru 7,62mm z wykorzystaniem wahadła balistycznego (WB). Badane materiały lite (1-warstwowe) i dzielone (2-warstwowe) w tej samej grubości w postaci krążków o średnicy 50 mm przestrzeliwano pociskiem kalibru 7,62 mm ŁPS lub B. Stwierdzono, że dla stali kadłubowej 2-warstwowe próbki materiału chronionego mają mniejszą odporność balistyczną niż 1-warstwowe (lite) w tej samej grubości przeciwnie do okrętowego stopu aluminium. Dzieląc stop aluminium na warstwy uzyskujemy znacznie lepszą OB. Lita stal Armox500 o grubości 7mm nie ulega perforacji pociskiem 7,62mmB podobnie jak 8mm grubości ceramika Al2O przestrzeliwana pociskiem 7,62mm ŁPS. Dzielenie Armox-u 500 obniża jego skuteczność ochronną.
MULTILAYER BALLISTIC SHIELDS FOR MARINE AND LAND MEANS OF MILITARY TRANSPORT
The paper presents the results of investigation on a ballistic resistance of Armox500 steel, aluminum alloy for shipbuilding and ship hull steel. Armox500 steel is utilized in the ballistic shields for means of military transport (land transport of type T and marine one of type S). Accordingly, the materials mentioned above were subjected to shooting with a bullet of the caliber 7,62 mm using a ballistic pendulum. Monolithic (single layer) and divided (double layer) materials of the same total thickness were in the form of disks having diameter equal 50 mm. The ŁPS bullet was used for testing the naval materials whereas the B was applied for Armox500.
It was found that the double layer ship hull steel exhibited worse ballistic resistance than the single layer sample of the same thickness. The opposite situation was discovered for aluminum alloy - dividing it into layers one obtains superior ballistic resistance.
Monolithic Armox500 steel of 7 mm thickness does not undergo perforation upon an impact of 7,62 mm B bullet. Similarly Al2O ceramic material of 8 mm thickness exhibits effective protection against 7,62 mm ŁPS bullet. Dividing Armox500 decreases its ballistic resistance. (...)
