Liquid armor is a material under research by defense institutions and universities around the world including the United States Army Research Laboratory (ARL). [ 1 ] [ 2 ] [ 3 ] Some of the earliest research in this area was performed at Massachusetts Institute of Technology [ 4 ] and University of Delaware [ 5 ] in 2003.
In 2002, researchers at the U.S. Army Research Laboratory and University of Delaware began researching the use of liquid armor, or a shear-thickening fluid in body armor. Researchers demonstrated that high-strength fabrics such as Kevlar can be made more bulletproof and stab-resistant when impregnated with the fluid.
The sudden application of force—by stabbing the surface with a finger, for example, or rapidly inverting the container holding it—causes the fluid to behave like a solid rather than a liquid. This is the " shear thickening " property of this non-Newtonian fluid.
The random nature of fragmentation required the military vest specification to trade off mass vs. ballistic-benefit. Hard vehicle armor is capable of stopping all fragments, but military personnel can only carry a limited amount of gear and equipment, so the weight of the vest is a limiting factor in vest fragment protection.
Liquid armor - The fabric might also be treated with shear thickening fluid, a mix of polyethylene glycol and nanoscale glass particles. This mix would function like chainmail , flexible with low speed motion such as running, but hard and solid against high speed motion such as that of a bullet impact, preventing serious injury or death.
Bullet-resistant body armor has been in use since about 1984. When law enforcement began wearing body armor, there was a dramatic drop in officer deaths, saving over 3,000 lives. [citation needed] The National Institute of Justice first developed standards for ballistic resistant body armor in the 1970s. The standards have been revised five ...
Both liquid and fixed assets play vital roles in financial planning. Liquid assets, such as cash reserves, provide a safety net for unexpected expenses, emergencies, or short-term financial needs.
The Soviet T-64 was the first mass-produced tank with composite armour The Leclerc tank is equipped with NERA (Non-explosive reactive armour) [1] Depending on the operating state, the Leopard 2 has various extended armour elements such as bomb protection for the top, cage armour, extended mine protection (A6M) or additional armour in the form of composite armour MEXAS or AMAP Plasan SandCat ...
