materials are sensitive to high temperature, humidity, radiation, ultraviolet (UV) light, etc., it is very important to study the durability and reliability of body armor.

There is a wide range of ceramics and ceramic-matrix composites that can be used in protection against projectile penetration. These ceramic materials can be divided into oxide ceramics (mostly, alumina ceramics with different contents of Al2O3) and non-oxide ceramics (mostly carbides, nitrides, borides, and their combinations) [9]. Alumina due to its high density (3.95 g cm−3), relatively high physical properties, low cost, and easy production is the most widely used oxide ceramics used to make ballistic materials [10]. Other types of non-oxide ceramic materials are carbides (e.g., silicon carbide-SiC and boron carbide-B4C) nitrides (e.g., silicon nitride-SiN) and borides (e.g., titanium diboride-TiB2). Enumerated non-oxide ceramics are more expensive than aluminum and a combination of different non-oxide ceramics is also possible [11–13].

Armor systems made of ceramics and composite materials are widely used in ballistic applications to repel armored missiles using materials with substrate properties and materials that minimize breakage. In order to make a quality ballistic composite, it is necessary to find the optimal composition and conditions to make them.
