The original specification for ballistic nylon was an 18 oz (510 g) nylon fabric made from 1050 denier high tenacity nylon yarn in a 2×2 basketweave. Today it may be any nylon fabric made with a "ballistic weave", typically a 2×2 or 2×3 basketweave. It can be woven from nylon yarns of various denier such as 840 denier and 1680 denier.
Kevlar (para-aramid) [2] is a strong, heat-resistant synthetic fiber, related to other aramids such as Nomex and Technora.Developed by Stephanie Kwolek at DuPont in 1965, [3] [2] [4] the high-strength material was first used commercially in the early 1970s as a replacement for steel in racing tires.
They are used in aerospace and military applications, for ballistic-rated body armor fabric and ballistic composites, in marine cordage, marine hull reinforcement, as an asbestos substitute, [1] and in various lightweight consumer items ranging from phone cases to tennis rackets. The chain molecules in the fibers are highly oriented along the ...
v 0 is difficult to measure, so a second concept has been developed in ballistic testing called the ballistic limit (v 50). This is the velocity at which 50 percent of the shots go through and 50 percent are stopped by the armor. US military standard MIL-STD-662F V50 Ballistic Test define a commonly used procedure for this measurement.
Twaron is a para-aramid and has automotive, construction, sports, aerospace, and military applications, e.g., in modern body armor, fabric, and as an asbestos substitute. Protective gear (heat resistant / ballistics) flame-resistant clothing, protective clothing and helmets, cut-fast or heat-hardy gloves, sporting goods, textiles, ballistic vests
Bullet-resistant materials (also called ballistic materials or, equivalently, anti-ballistic materials) are usually rigid, but may be supple. They may be complex, such as Kevlar, UHMWPE, Lexan, or carbon fiber composite materials, or basic and simple, such as steel or titanium. Bullet resistant materials are often used in law enforcement and ...
