From the Ministry:
The developers call it a “sheer-thickening liquid,” one which stiffens instantly when struck, and then re-liquifies instantly once the stress is gone…
Armor Holdings, inc., a company until now primarily concerned with supplying the Army with vehicle armor, bought the rights to this technology, and hopes to be selling suits of liquid armor by early next year. At first, Wagner thought that the liquid armor might be applied almost like peanut butter, in a relatively thick layer. But experimentation showed that the greatest protective effect was achieved by applying many very thin layers of the liquid to sheets of Kevlar. The sheer-thickening effect of the liquid is enhanced when the liquid is embedded in layers of Kevlar – the force of a blow is spread wider, resulting in greater protection for the wearer. By greatly enhancing the stopping power of Kevlar – less is needed.
This has been talked about off and on for some time. More info on this and other advanced armor technologies.
