New Body Armor Passes Tests


From the US Patent Office website,

Experimental testing has demonstrated that the system 100 is effective to defeat an AP bullet fired from a rifle at point-blank range (e.g. at impact V.sub.p.apprxeq.850 meters/second). Applications include, but are not limited to, body armor for infantry soldiers and law enforcement agencies, integral armor or armor appliques for vehicles such as aircraft, helicopters, and cars. Other uses include military applications, such as used in conjunction with ground vehicles or amphibious assault vehicles. Thus, the system 100 for protection against a projectile 105 having a speed, or velocity V.sub.p, comprises an accelerating layer 110, a plug layer 120, and (optionally) an energy absorbing layer 130. Typically, the plug layer 120 is planar to the accelerating layer 110 and the energy absorbing layer 130 is planar to the plug layer 120. The plug layer 120 includes at least one plug 140. These layers may be adjacent with perhaps an air gap between, but the same concepts could be applied to embodiments with intermediate layers. It is also possible to make the layers non-planar, such as for conforming or conformable clothing or other armoring.

  1. And if it doesn’t work, just reading the specs is a terrific soporific.

  2. Can’t tell by the names on the patent form, if they are involved in any of the other body armor projects, but there are many.

  3. Completely off topic for those that did not know where that stuff that bears do in the woods goes:

  4. Well, I’m sure the Romans would have approved. http://www.swordsofhonor.com/romanarmor.html

    Guess I’ll have to go back to reading the specs to see if it says anything about broadwords, maces, or really big effing rocks.

  5. Whoa, that’s a good illustration of the dragon armor. Hooray for 21st century chain mail!

  6. And it also demonstrates the capabilities of CNC routers to do 3-D work.

  7. And speaking of CNC routers, there’s one waiting on me right now. Later!
