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.
The Improved Outer Tactical Vest (IOTV) in MultiCam, as issued to United States Army soldiers. A bulletproof vest, also known as a ballistic vest or bullet-resistant vest, is a type of body armour designed to absorb impact and prevent the penetration of firearm projectiles and explosion fragments to the torso.
The VPAM scale as of 2009 runs from 1 to 14, with 1-5 being soft armor, and 6-14 being hard armor. [1] Tested armor must withstand three hits, spaced 120 mm (4.7 inches) apart, of the designated test threat with no more than 25 mm (0.98 inches) of back-face deformation in order to pass.
Kevlar in non-woven long strand form is used inside an outer protective cover to form chaps that loggers use while operating a chainsaw. If the moving chain contacts and tears through the outer cover, the long fibers of Kevlar tangle, clog, and stop the chain from moving as they get drawn into the workings of the drive mechanism of the saw.
The soft kevlar panels have been tested to stop 9 mm 124 grain full metal jacket bullets at 1,400 ft/s (426 m/s) with minimal deformation and has a V-50 of roughly 1,525 ft/s (465 m/s). This means that the bullet has to be traveling faster than 1,525 ft/s (465 m/s) for it to have more than a 50% chance of breaking through the soft armor panel.
Kevlar KM2 is a synthetic para-aramid fiber produced by DuPont. The fiber is an evolution of the original Kevlar fiber. The following quotes summarize Kevlar KM2's ...
The basic issued variant of 6B45 has a weight of approximately 8 kg. The basic issued variant of the body armor includes: a body armor cover (with MOLLE system on front sides and back), a collar protecting against fragments, anti-fragmentation bags on the sides with a fairly large protection area, rear and front class 5A armor plates, an emergency release device and a removable ventilation and ...
To effectively stop a blast wave, thick layers of Kevlar, foam and plastic are needed to prevent serious bodily harm. Since the entire body needs protection, the resulting bomb suit is heavy (80 lb (36 kg) or more), hot to the point of risking heat stress, and impairs movement. Therefore, often one individual will put on a suit to approach a ...
