THE INFLUENCE OF THE GEOMETRIC FACTOR ON THE BALLISTIC STRENGTH OF THE ADDITIONAL COMPOSITE ARMOURED SYSTEMS

Armour hybrid sandwich structures containing ceramic layers are used increasingly for the protection against high speed penetration projectiles. The negative effect caused by the breaking of the ceramic material at the impact with the high speed penetration projectile is mitigated by using several ceramic plates instead of a plate block for the armour manufacture. Although initially there have been used square ceramic plates, this work shows that the use of hexagonal ceramic plates increases both the strength of the ballistic armour, and its flexibility.
