Advanced Composite Materials Have Specific Longitudinal Stiffness And Strength

Ballistic Materials are the substances used to protect a person from projectiles, bullets and other munitions. These materials are usually produced with 70kg/m3 density. They are usually designed with a Back Face Signature of 40mm and have impact protection underneath. These materials have been tested and show maximum transmitted forces that were greater than 11 kN. Core Matrix Technology has been developed by Tex Tech Industries. It is a loosely locked down layer of ballistic materials using Z directional staple length fibers. This technology has been tested in combat shirts and found to be 20% lighter than current specifications. Tex Tech executives claim that this technology won’t affect the performance or mobility of the shirt.

They are especially appealing in applications where weight is a factor. Composite materials typically use high-performance fibers in various orientations to improve specific lengthening stiffness and strength. They are often used in structural applications. Textile armor systems are becoming popular as protection against impact in heavy-duty environments. Personal protective gear is susceptible to the impact of handgun bullets and fragments of bomb shells that explode. The armor made of textile and composite can be used to lessen the weight and improve the effectiveness of impact.

Para-aramid fibers and ultra-high-molecular-weight polyethylene are the traditional materials used in ballistic textiles. But the rapidly evolving nature of warfare has required the industry to speed up the pace of innovation. 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.

Although some ballistic fabrics have the same peak transmitting strength as the plate used in the test, their actual strength varies greatly. Kevlar KM2 r has a strength of 400 denier and CF42 and can be able to withstand forces that peak at 749 N. Its durability and reliability have been proven through various tests. It is important to understand the role of ballistic materials for a particular mission.

The US Department of Defense (US DOD) has published two methods to improve the core of rifle bullets hardness. The Enhanced SAPI plates are able to endure 7.62×63 AP(M2) bullets that feature an engineered core. Military engineers have identified patterns in the distribution of fragment velocity that can be used to determine the effectiveness of warheads. These patterns can be broken down into useful concepts. For example, a Rc35 steel rifle bullet can be considered armor-piercing under military engineering standards.

Human tissue is a vital component of flexible armor, as it absorbs high energy impact. Human torso tissue is extremely compliant, but has a strong backside signature. In contrast, the hardness of sternum bones as well as muscles suggests that this type of material is a less suitable material to be used in ballistics. The back side signature of armor is essential. The energy delivered by non-penetrating weapons can be used to measure the back side signature of soft armor.
