Armours where the main protective mechanism is to erode the projectile (not fracture or rotate it, as in e.g. reactive armours) are usually called consuming armours. The materials used for this type of armour are mainly metals or ceramics: metals since they are construction materials with good protection properties and ceramics since they, used in a proper way, are very weight-effective protection materials. Ceramic armours against KE-projectiles are discussed and two potentially very important development-trends are presented: - ceramic armours for where the projectile is defeated. on the surface of the ceramic material without any notable penetration, interface defeat or dwell. - ceramic armours where the virgin strength of the ceramic can be sustained even during penetration, enhanced penetration resistance.
