Ballistic Materials are substances which protect people from the impact of projectiles and bullets. They are usually produced with a density of 70 kg/m3. They are designed to have a Back Face Signature of 40mm and impact protection beneath. The materials have been tested and showed maximum transmitted forces of over 11 kN. Tex Tech Industries has developed Core Matrix Technology, which loosely locks down layers of ballistic materials with Z-directional staple length fibers. This new technology has been tested in combat shirts and has been shown to be able to meet current standards with a 20 percent reduction in weight. Tex Tech executives claim that this technology will not compromise performance or mobility.
Advanced composite materials possess high specific longitudinal stiffness and strength and are particularly attractive in applications where weight is an issue. Commonly, composite materials employ different orientations of high-performance fibers in order to enhance specific longitudinal stiffness and strength. They are often used in structural applications. Textile armor systems are becoming more popular as protection against impact in environments that require weight. Bullets from handguns and fragments of exploded shells are typical threats to personal protection items. Utilizing composite and textile armor systems can help reduce the weight of these materials while increasing impact performance for a given weight.
Para-aramid fibers and ultra-high-molecular-weight polyethylene are the traditional materials used in ballistic textiles. The rapid evolution of warfare has compelled the industry to innovate faster. In response, raw materials suppliers have enhanced high-tensile-strength ballistic fibers and worked with textile manufacturers to develop lighter fabrics that block high-power rifles, IED fragments, and backface trauma.
Despite the fact ballistic materials have the same peak transmitted force as the plate used in a ballistic test the actual strength of the materials varies considerably. Kevlar KM2 r has a strength of 400 denier and CF42, and can be able to withstand forces that peak at 749 N. Its reliability and durability have been proven by numerous tests. It is essential to understand the role of ballistic materials in a given mission.
The US Department of Defense (US DOD) has released two options to increase the hardness of rifle bullets. The enhanced SAPI plates are able to endure 7.62×63 AP(M2) bullets with an engineered core. In analyzing the efficiency of the warhead, military engineers have identified characteristic distributions of fragment velocities, which can be broken down to useful concepts. Military engineering standards could classify an Rc35 steel rifle shot as an armor-piercing.
Human tissue is an integral component of flexible armor, since it absorbs high energy impacts. The tissues of the torso of the human body is extremely flexible, but it has a high back signature. The toughness of the sternum bones and muscles means that this material is a less suitable material for ballistics. The back side signature of armor is crucial. Additionally the signature on the back side of soft armor is usually measured by measuring the energy generated by projectiles that do not penetrate.
