This armor would protect against three hits, fired from 5±0.5 meters in an angle of 25°, as well as 3 shots at point-blank, of: 8.0±0.1 g (123±1.54 gr) 9×19mm Parabellum DM41 FMJ round-nose lead-core bullets at a velocity of 415±10 m/s
The OTV features a carrier shell, and three main (flexible) ballistic panel inserts (front left and front right panels, and a rear back panel), [4] which are made with a finely woven Kevlar KM2 fiber. These two parts of the vest are both bullet and heat resistant and offer protection similar to the earlier PASGT flak jacket.
An insert to protect the spine is usually applied to the back, in case an explosion throws the wearer. Visibility and mobility of the wearer is severely limited, as is the time that can be spent working on the device. Armor designed primarily to counter explosives is often somewhat less effective against bullets than armor designed for that ...
Nearly all modern military body armor is designed to prevent penetration from bullets to vital areas of the body, in addition to protection against knives and fragmentation from explosives. Typically this is accomplished through both highly durable woven synthetic fibers such as Kevlar or Dyneema, and either metal or ceramic ballistic plates ...
Fabric panel (level II protection) in the back is made of 30 layers of TSVM-2 Kevlar-like material and provides protection against bullets from TT pistol (cartridge 57-N-134S) and PMM (cartridge 7N16) from 5 meters, has increased anti-fragmentation resistance (fragment weighing 1 g at a speed of 600 m/s, 50 %,). [1] [5] Weight is 4 kg. [2]
The fiber is an evolution of the original Kevlar fiber. The following quotes summarize Kevlar KM2's properties. "DuPont created Kevlar KM2 to achieve the performance goals defined by casualty reduction testing for the United States Department of Defense. Today it is used extensively for fragmentation protection in the U.S. military. Helmets and ...
These experiments visually showed that liquid armor has ballistic properties that are greater than neat fabrics. It was displayed that only four layers of STF-Kevlar offer the same amount of protection that ten layers of standard Kevlar offers. Additionally, it was discovered that STF-Kevlar has little to no increase in thickness and stiffness.
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.
