International NIJ Protection Classes

Survival in combat systems can be considered to depend on three basic parameters such as firepower, protection and mobility. In attack systems, one of the most important branches of combat systems, with the development of ballistics science, weapon structure and high-performance bullet tips have been developed, and the rate of fire has been greatly increased. As a result, the ability to penetrate protective armor has also increased. In response to this development in combat systems, defense systems are also necessarily evolving. The level of protection of armor systems, one of the most important branches of defense systems, has also been increased with the development of ballistics science. With advanced studies, armor materials have been developed to provide protection against various threats with minimum weight.

Ceramics and polymer composite materials are being investigated by various researchers to design ultra-light and high protection armor. Advanced fiber-reinforced laminates such as aramid, glass and ultra-high molecular weight polyethylene (UHMWPE) are used in both add-on and structural composite armor applications, both independently and as a support for ceramic armor.
