Silica is a component of sand and quartz, and polyethylene glycol is a polymer commonly used in laxatives and lubricants. The silica particles are only a few nanometers in diameter, so many reports describe this fluid as a form of nanotechnology. To make liquid body armor using shear-thickening fluid, researchers first dilute the fluid in ethanol.

An armor composite material has been invented which contains a fabric which has been impregnated with shear thickening fluid. This invention offers a ballistic resistant material that is more flexible and less bulky than comparable, conventional ballistic fabric. The material in the alternative can be puncture resistant. The invented material offers superior ballistic …
The most popular choice of STF in high-performance fabric applications is colloidal fumed silica dispersed in polyethylene glycol (PEG) (Decker et al., 2005;Gürgen and Kuşhan, 2017b;Hasanzadeh ...
The higher energy rounds .500s&w, 10mm, 44mag will still cause excessive trauma so the soft armor needs a backer such as memory foam to absorb the impact. All you need is Kevlar ballistic grade (you can buy new panels or buy an old flak jacket) Polyethylene Glycol 200 (200 Molecular weight, DOT 3 Brake Fluid)
Polyethylene glycol (PEG) and polyethylene oxide (PEO) are polymers composed of repeating subunits of identical structure, called monomers, and are the most commercially important polyethers.Poly (ethylene glycol) or poly (ethylene oxide) refers to an oligomer or polymer of ethylene oxide.The two names are chemically synonymous, but historically PEG has tended to …

Development of Stab Resistant Body Armor Using Fumed SiO2 Nanoparticles Dispersed into Polyethylene Glycol (PEG) through Sonic Cavitation H. Mahfuz, F. Clements and J. Stewart Nanocomposites Laboratory, Department of Ocean Engineering, Florida Atlantic University, Boca Raton, FL 33431, [email protected] ABSTRACT
The core feature of liquid armor is a shear thickening fluid composed of hard particles suspended in a liquid. The liquid, polyethylene glycol, is nontoxic and can withstand a wide range of temperatures. Hard, nanoparticles of silica constitute the other component of the liquid.
Liquid Armour is a material under research by defense institutions and universities around the world including the United States Army Research Laboratory (ARL). Some of the earliest research in this area was performed at Massachusetts Institute of Technology and University of Delaware in 2003. Liquid armor was initially presented as a way to increase the survivability of soldiers …
The resulting product they created was the AIMX-02 "IronSkin" Subdermal Body Armor, a next step they feel in the field of concealed body armors. The IronSkin Body Armor is created by implanting 2mm thick graphene lattice weaves reinforced by carbon nanotubes and suspended in a polyethylene glycol and slilicon dioxide solution under a …
Particles were dispersed in the polyethylene glycol, through a combination of shear mixing homogenizer at 8000 RPM and ultra-sonication (Bandelin HD3200). The impregnation of the Kevlar fabric yarns for the preparation of the STF-Kevlar composite target, is facilitated by diluting STF in ethanol at a 1:2 vol ratio and individual fabric layers ...

Polyethylene glycol (PEG) is a biocompatible, synthetic, hydrophilic polyether compound that has many applications, mostly in the medical industry, but also in the chemical and industrial sectors.
Answer: This is precisely the sort of engineering problem that, if you knew the answer to it, you would be making big money selling it to a defense contractor rather than posting the answer all over the Internet. Somehow I expect there is more nuance to the process than it …

"Liquid body armor" or sheer thickening fluids are made of liquid, polyethylene glycol and hard silica particles. The US Army is currently testing pre-soaked STF Kevlar body armor. Hagfish slime is being researched for soft body armor because of …
Shear thickening fluid, commonly known as STF or liquid armor is a new, emerging technology in the military-protection industry. This liquid composite is currently being tested and developed by the U.S. Army Research Laboratory.More specifically, STF is composed by polyethylene, non-toxic glycol, and particles of silica.
Liquid Armor In Two Flavors: Shear Thickening and Magnetorheological. Liquid armor using shear thickening fluid (STF) is being developed at the U.S. Army Research Laboratory at Aberdeen Proving Grounds. The STF referred to in this article is made up of hard silica particles suspended in polyethylene glycol, a non-toxic fluid.

Polyethylene glycol (PEG) is an inert amphiphilic polymer in contrast to ethylene glycol oxide, which is commonly known as a toxic compound used for synthesis of PEG. A consequence of its low reactivity is that PEG does not exhibit toxicity in humans also because mammals do not have enzymes which are able to metabolize PEG.
