Foam body armor? Even armor-piercing bullets cannot get through this foam.

And the foam doesn’t just stop bullets. It destroys them…this foam decimates bullets into dust.

North Carolina State University Professor Afsaneh Rabiei led the team that created the amazing foam.

This is not ordinary foam like the kind used for shaving, for example. This is a special type of foam called composite metal foams, or CMF.

guess that made my next book sound obsolete already....

Because it was only first draft, I can add something like this. ha

This is not ordinary foam like the kind used for shaving, for example. This is a special type of foam called composite metal foams, or CMF.

To make it, the team takes molten metal and bubbles gas through it. This process creates a sort of froth. When the froth cools, it becomes a lightweight, ultra strong matrix material.

Processes like 3D printing and milling can also be used to make composite metal foam.

I wish they would have discussed cost.  This technology shows promise if affordable.
