Metal Foam? In Body Armor?

Metal_FoamEver heard of “Composite Metal Foams” (CMFs)?  Turns out, this technology has been around for quite a while and has a wide range of applications.  These materials are tough enough to turn an armor-piercing bullet into dust on impact but weigh a fraction of plate armor.

Afsaneh Rabiei, a professor of mechanical and aerospace engineering at NC State, has spent years developing CMFs. The video below shows a specimen made out of her composite metal foams. The bullet in the video is a 7.62 x 63 millimeter M2 armor piercing projectile, which was fired according to the standard testing procedures established by the National Institute of Justice (NIJ).  As you can see, the results were dramatic.

“We could stop the bullet at a total thickness of less than an inch, while the indentation on the back was less than 8 millimeters,” Rabiei says. “To put that in context, the NIJ standard allows up to 44 millimeters indentation in the back of an armor.”

Machine Domination… We told you so…

Atlas-p3

Sleep tight, Master… I’ll be watching!

Friends, as previously reported, the machines will soon be tucking your kids into bed at night and waiting to snap your neck after it receives the command from SkyNet.  Google has recently bought a half dozen robotics companies and one that works in artificial intelligence. Among those companies is Boston Dynamics, which has designed robots for the military that can run like a cheetah and climb vertical walls. Did I mention they also have a humanoid “Atlas” robot that, although not specifically designed for any offensive military use, can withstand being hit by projectiles and looks an awful lot like a predecessor to what we’ve seen in the “Terminator” series? Connect Atlas up to Google Now and you’ve got a bulletproof robot with a pet robotic cheetah that knows where you live and travel and what your interests, plans, and even musical tastes are.  Perhaps we’re over reacting, but if I saw a fire team of these robots coming down the street going door-to-door looking for their human oppressors, I’d probably be breaking out my Barrett .50 and taking up a position on the roof.  Check this out; kinda creepy…
