Technology Marketing SummaryThe primary purpose of the "Kevlar Gauntlet" is to provide military personnel with much needed, lighweight protection while in combat.  A particular threat to U.S. soldiers are rocket propelled grenades (RPGs) and improvised explosive devices (IEDs) which can create significant risks to safety as a result of debris, shrapnel, spall, superheated air blasts, and shock waves.  The gauntlet, which can be worn on the arms for soldiers operating atop Bradley Fighting Vehicles and armored HUMVEEs, will protect the soldiers' exposed arms and shoulders which are not protected by traditional body armor vests.  Alternately, the gauntlets can be worn on the legs as protection inside a vehicle that may not have armored doors or any doors at all. DescriptionThe lightweight armored garment is made of a ballistic fabric such as KEVLAR (registered) along with more rigid armored carbon composite inserts that protect against high-velocity projectiles, shrapnel, and spall.  The combination of these layers meets level IIIA fragmentation minimum for the US Interceptor Outer Tactical Vest. Benefits
  • Lightweight protection that can be worn on upper or lower limbs
  • Carbon-composite inserts mitigate blunt force trauma, penetration, or shredding that can be caused by firearms, explosives, and debris
  • KEVLAR (registered) provides heat protection along with similar protection characteristics of the carbon composite
Applications and Industries
  • Body armor
  • Weapons protection
  • Outdoor sporting protection

Armored garment for protecting
A lightweight, armored protective garment for protecting an arm or leg from blast superheated gases, blast overpressure shock, shrapnel, and spall from a explosive device, such as a Rocket Propelled Grenade (RPG) or a roadside Improvised Explosive Device (IED). The garment has a ballistic sleeve made of a ballistic fabric, such as an aramid fiber (e.g., KEVLAR.RTM.) cloth, that prevents thermal burns from the blast superheated gases, while providing some protection from fragments. Additionally, the garment has two or more rigid armor inserts that cover the upper and lower arm and protect against high-velocity projectiles, shrapnel and spall. The rigid inserts can be made of multiple plies of a carbon/epoxy composite laminate. The combination of 6 layers of KEVLAR.RTM. fabric and 28 plies of carbon/epoxy laminate inserts (with the inserts being sandwiched in-between the KEVLAR.RTM. layers), can meet the level IIIA fragmentation minimum V.sub.50 requirements for the US Interceptor Outer Tactical Vest.
