Ceramic Tank Armour

Ceramic armor is armor used by armored vehicles and in personal armor to resist projectile penetration through high hardness and compressive strength.

Ceramic tank armour.

Other names informally given to chobham armour include burlington and dorchester. Chobham armour is the informal name of a composite armour developed in the 1960s at the british tank research centre on chobham common surrey. Ceramic material shatters as the heat round penetrates the highly energetic fragments destroying the geometry of the metal jet generated by the hollow shaped charge greatly diminishing the. Thus it is necessary that the ceramic material presents high elastic modulus and high hardness 2.

A relatively famous form of composite armor is so called chobham armor that sandwiches a layer of ceramic between two plates of steel armor and is used on main battle tanks such as the abrams. Ceramic armor is armor used by armored vehicles and in personal armor for its attenuative properties. Ceramic materials for using as ballistic armor must be sufficiently rigid to fragment the bullet and reduce its speed transforming it into small fragments that should be stopped by the layer of flexible material that supports the ceramic. The core armor is a variation on the british chobham armor an arrangement of metal plates ceramic blocks and open space.

Composite armor plates are lighter thicker and more flexible than steel plates. Ceramics offer an advantage over steel in weight reduction and over all metals in impact energy absorption. Heat and sabot rounds may make it through the outer layer of the armor but they won t make it all the way into the crew compartment. In hard armor with ceramic inserts the kinetic energy of the projectile is absorbed and dissipated in localized shattering of this ceramic tile and blunting of the bullet material during its impact on the hard ceramic.

The ceramic material can absorb a lot of heat as well as heavy physical blows. Most ceramic composite body armor plates cannot withstand multiple hits to the same area. The most common ceramic materials used for armor applications are alumina boron carbide silicon carbide and titanium diboride. The strongest and lightest ceramic is boron carbide.

Ceramic armor can be used to protect vehicles as well as individual personnel and dates back to 1918. Ceramics are known to be some of the of the hardest materials and unlike materials such as kevlar which uses its fibers to catch the bullet ceramics break the bullet.
