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 ballistic panels are covered in a coated pouch or slip. This slip provides the encapsulation of the ballistic materials. Slips are manufactured in two types: heat sealed hermetic slips and simple sewn slips. For some ballistic fibers such as Kevlar the slip is a critical part of the system. The slip prevents moisture from the user's body ...
[6] [1] Shubin received a $5 million grant to research the use of the fabric in bullet-proof vests. In 1975, the federal government distributed 5,000 Kevlar vests to 15 police departments. In the first year of deployment, two police officers wearing the vests were shot with handguns and two others were attacked with knives.
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 properties. "DuPont created Kevlar KM2 to achieve the performance goals defined by casualty reduction testing for the United States Department of Defense.
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 ...
