An investigation of the effect of a Kevlar-29 composite cover layer on the penetration behavior of a ceramic armor system against 7.62 mm APM2 projectiles

High hardness ceramics are commonly used in lightweight armor systems to defeat the intrusion of high-speed armor piercing (AP) projectiles. However, bare ceramic tiles are intrinsically brittle, and fragments of various sizes can be generated when subjected to impact, which can cause secondary impact to the wearer and surroundings. In a typical armor design, the ceramic tile is usually covered with a compliant thin sheet to mitigate fragments...
