Results are presented from ballistic tests and studies of mosaic ceramic elements in the external layer of armor
panels made by the French company “ARES Protection SAS” with a level-IV protection rating.

The requirement that armor be bullet-proof has recently
been supplemented by the requirement that it also be highly
rated for survivability, which characterizes the ability of an
armored structure to retain its protective properties when it
has sustained several types of damage. This need has been
addressed in recent years by the development of armor in the
form of mosaic ceramic elements (MCEs) secured in an elas-
tic matrix. In contrast to structures that employ monopanels
and ceramic slabs, mosaic armor  can withstand up to five
bullet impacts per square decimeter and can easily be re-
paired under field conditions. The fragmentation of a unit el
ement of the ceramic localizes the damage region, while the
absence of rigid connections between the elements helps dis
sipate the energy of impact and facilitates the structure’s
Composite armor with MCEs is used both for individual
protection and on specialized equipment: armored vehicles,
combat helicopters, and ships. The flexibility of composite
armor allows it to be used to cover surfaces of complex
shape in hard-to-reach locations, with the metal housing of
the equipment that is being protected serving as the founda
tion. At the exhibition “Interpolitech-2008,” the company
“Omnitek-N” displayed protective panels made by the
French firm “ARES Protection SAS for different levels of
protection (Fig. 1a ). The ceramic front layer of these panels
is in the form of a mosaic (Fig. 1b ).
An analysis of information on the use of protective armor
in Russia and abroad over the last 20 years revealed the exis
tence of more than 50 patents for mosaic armor. The leading
