Transparent Armor

From Air Force Link

Engineers here are testing a new kind of transparent armor -- stronger and lighter than traditional materials -- that could stop armor-piercing weapons from penetrating vehicle windows.

The Air Force Research Laboratory's materials and manufacturing directorate is testing aluminum oxynitride -- ALONtm -- as a replacement for the traditional multi-layered glass transparencies now used in existing ground and air armored vehicles.

The test are being done in conjunction with the Army Research Laboratory at Aberdeen Proving Grounds, Md., and University of Dayton Research Institute, Ohio.

ALONtm is a ceramic compound with a high compressive strength and durability. When polished, it is the premier transparent armor for use in armored vehicles, said. 1st Lt. Joseph La Monica, transparent armor sub-direction lead

"The substance itself is light years ahead of glass," he said, adding that it offers "higher performance and lighter weight."
