Ceramic armor is armor used by armored vehicles and in personal armor to resist projectile penetration through its high hardness and compressive strength. In its most basic form, it consists of two primary components: A ceramic layer on the outer surface, called the "strike face," backed up by a ductile fiber reinforced plastic composite or metal layer.
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 ]
