HuffingtonPost ha scritto:Transparent Aluminum Armor
What starts as powder and suddenly becomes so powerful it can withstand bullets? Well, with a little bit (OK a lot) of heat and pressure: the latest in transparent armor.
Lighter and even stronger than bulletproof glass, the Air Force has been testing aluminum oxynitride (ALON) in hopes of replacing windows in its aircraft. And judging by the fact that the clear ceramic material can stop a .50-caliber rifle’s bullet travelling 2,700 feet per second — normally powerful enough to slice through a lightly armored vehicle like butter — we’d say that’s a more-than-justified investment.
Mica male... Quanto costerà rifarci i vetri di casa "antisasso"?
