I found this last month, so it's slightly old news, but still news. The material in question is composite metal foams, which in addition to being so strong that they literally destroy armor-piercing bullets, are also superior in thermal resistance and presumably weight (by virtue of not being entirely solid). Here's the link and a blurb:
Composite Metal Foams (CMFs)
The new material was developed by researchers at North Carolina State University, finding that the CMFs had an excellent thermal protection, when being compared to regular metal and it managed to turn armor piercing bullets into dust when in touch with the material.
The team studied the lightweight of the CMFs and found that it possessed air pockets inside the metal foams. These air pockets are able to block the heat of the upcoming impact.
The CMF’s are made from what researchers call “composite metal foam” that acts as an armor able to destroy bullets created to pierce what is set upfront.
Do you think this might see widespread use in body armor in the 2020s and beyond, possibly in addition to nanotech materials like nanotubes and graphene? Perhaps it could be incorporated into my hypothetical smart armor, or the Tactical Assault Light Operator Suit.
