Ceramic armor systems defeat small arms projectiles and kinetic energy penetrators by two main mechanisms: Shattering and erosion. When a hard steel or tungsten carbide projectile hits the ceramic layer of a ceramic armor system, it is momentarily arrested, in a phenomenon known as dwell. Depending on the thickness and hardness of the ceramic ...
The Soviet T-64 was the first mass-produced tank with composite armour The Leclerc tank is equipped with NERA (Non-explosive reactive armour) [1] Depending on the operating state, the Leopard 2 has various extended armour elements such as bomb protection for the top, cage armour, extended mine protection (A6M) or additional armour in the form of composite armour MEXAS or AMAP Plasan SandCat ...
The relative interface defeat component of the protective value of a ceramic is much larger than for steel armour. Using a number of thinner matrices again enlarges that component for the entire armour package, an effect analogous to the use of alternate layers of high hardness and softer steel, which is typical for the glacis of modern Soviet ...
MIL-DTL-46100E specifies a steel of identical hardness. [3] MIL-DTL-32332 specifies ultra-hard steel, with Brinell hardness in excess of 570. [3] A Chinese publication lists 30MnCrNiMo "685" steel as the material used in Chinese rolled armor plates, with a Brinell Hardness of HBW 444-514 (thin) / 429-495 (thick).
For example, the T-64 turret had a layer of ceramic balls and aluminum sandwiched between layers of cast steel armour, [10] whilst some models of the T-72 features a glass filler called "Kvartz". The tank glacis was often a sandwich of steel and some low density filler, either textolite (a fibreglass reinforced polymer) or ceramic plates. [ 11 ]
Advanced Modular Armor Protection (AMAP) is modular composite armour concept, developed by the German company IBD Deisenroth Engineering, since 2019 part of Rheinmetall Protection Systems. According to IBD AMAP is a 4th generation composite armour, making use of nano-ceramics and modern steel alloy technologies. [ 1 ]
Combination K is a three-layer composite armor consisting of an outer and inner layer of steel and a middle layer of fiberglass glass-reinforced plastic ("steklotekstolit") and a pack of ceramic (allegedly corundum) plates.
Ceradyne was founded in 1967 [3] and in late 2004, the company added new product lines by acquiring ESK Ceramics of Kempten, Germany. [4]In addition to producing ceramic components for industrial processes such as silicon foundries and ceramic fuel pellets for nuclear reactors, Ceradyne researched and produced varieties of ballistic armour for both personnel and vehicles.
