Novel PBA-Grafted Carbon Nanotube Soft Body Armor

  • Future tech: Ballistic armor made of wood?

    Nov 19, 2012· Since soft body armor has been available for police for roughly 40 years, we don’t pay much attention to it. Developments in this industry are more apparent when you have the perspective of most of that history, and remember when a plain vanilla Level II vest without a trauma plate was almost as bulky as the external body armor the military presently uses.
