Liquid armor hardens in contact with bullets

by Mark R

What you see there is a bullet-proof vest, and I’ve just learned that even the best ones cannot completely keep bullets out. However, this one model could change all of that.

This model uses “custard-like goo” that somehow makes molecules lock together when it is hit. I’m going to assume that makes it really, really hard.

Apparently, these “shear-thickening liquids” have been used by downhill skiers in order to prevent broken bones and injuries, and, even though it would seem obvious, this is the first time it is being used as armor.

I don’t know about you, but this technology sounds like something that Wayne Enterprises would have in its basement in Batman Begins. After all, Lucius Fox (Morgan Freeman’s character) had this very expensive bullet-proof vest as well as some “memory cloth”. That memory cloth was the stuff that made Batman’s cape go all hard and like a glider. I don’t see why Mr. Fox wouldn’t be working on some bulletproof custard.

Bulletproof custard. Man, that sounds like an item from a desert menu at a school cafeteria. At least, that is what the students would call it.

Well, I’m sure that if this tech works, then all the cops will probably be wearing these bulletproof vests filled with this goo. Hopefully they will not leak.

The custard is not a custard. It is more a hardening fluid, and it is in the non Newtonian fluid category. The non Newtonian can be defined in mainly two categorizes. The first is a fluid that with no movement goes from what would seem a thin viscosity to a thick viscosity, an example is ketchup. when ketchup is left unattended it becomes think, but when shaken it becomes thin, as in after you shank the bottle you can apply the red substance to your food. Well in reference to the Custard like fluid refereed to in the article. This type of non Newtonian fluid becomes thicker when force is exerted upon it. non Newtonian fluid is not measured in viscosity but rather it is measured according to a shear factor. In normal Newtonian type fluids different fluids are categorized by viscosity. take for instance your automobile. The engine might take a oil with a 10w 30 viscosity rating while your differential may take 80w or 75w 90. the dual viscosity ratings are influenced by the thermal temperature of the fluid, so for instance when the engine is cold with 10w 30 the engine oil is a thinner viscosity like 10 on the measuring system so the oil pump can pick up the oil and move it to where it is needed faster then a thicker oil can move to provide lubricating protection faster.
well with non Newtonian fluid it if not influenced by temperature. It becomes thicker when impacted. i had to refer back to some old martial I have read, the fluid is also refereed to a shear thickening fluid. In London a military armor dealer has developed a set of bullet prof armor that took the average layers in the vests being used from 30 layers down to 10 layers. the 10 layers can stop higher powered artillery and can effectively stop more hits then the standard armor. their are now multiple company’s manufacturing these sets of armor and the cool thing about them is they are lighter they can flex with the body. sorry about the ramblings I seem to do that when i am excited about things.
