Abstract: An armor assembly for mounting to a vehicle to protect it from an expected explosion. The assembly comprises at least two layers, each contacting an adjacent layer. One of said layers is a perforated layer and another one is a covering layer. The perforated layer is made of a material of a first density, and having a first surface configured to face towards the vehicle when the armor assembly is mounted thereto, and a second surface opposite thereto. The perforated layer is formed with holes each having an opening at least at said second surface. The covering layer is made of a material of a second density which is greater than the first density and is configured to be permanently bent by said explosion into the openings, at opening covering portions of the covering layer, to such a depth as to restrict sliding movement at least between the two layers.

Abstract: An armor assembly configured to be mounted to a vehicle to protect it from an expected explosion. The armor assembly comprises at least two layers, each contacting an adjacent one of said layers. One of said layers is a perforated layer and another one is a covering layer. The perforated layer is made of a material of a first density, and having a first surface configured to face towards the vehicle when the armor assembly is mounted thereto, and a second surface opposite thereto. The perforated layer is formed with a plurality of holes each having an opening at least at said second surface. The covering layer is made of a material of a second density which is greater than the first density and is configured to be permanently bent by said explosion into the openings, at opening covering portions of the covering layer, to such a depth as to restrict sliding movement at least between the two layers.
