Functionally and Geometrically Ordered Ti Armor

 

Ballistic Tests for Ti Composite Armors

2: Ballistic Tests

Ballistic testing was conducted on a variety of graded and geometrically complex armor tiles have been tested versus the .30 cal. APM2 armor piercing round.

The test results were compared to both conventional wrought titanium armor and monolithic powder metallurgy titanium plates. Examples of armor tiles that underwent ballistic testing are shown in the figures below. Also shown is a graphical summary of the test results for the various types of armor that were tested.
