Abstract: A protective device is provided that includes material strips made of at least two different materials, wherein the thickness of the strips is considerably larger than the height and the height of the strips is at least half as large as the calibre of the explosively formed projectile and both materials have considerably different strengths. The alignment of the sandwich composition is such that the material layers arranged on top of each other face the impact direction. Thus, a projectile designed in the direction of the protective structure shears off and no longer slide through the protection in a straight manner.
