1. Liquid “Armor” on Kevlar

2. Problem
Current bulletproof vests
only protect around the
chest area while rest of
the body is an open
target.
Many soldiers are injured
during war. There were
18,356 injuries in the
current war with Iraq as
of June 11, 2006

3. Solution
Scientist came up with
something called “liquid armor”
Liquid armor is a type of liquid
which stiffens when agitated to
prevent anything from
penetrating.
A thin layer of this liquid is
designed to be enclosed in
clothes to prevent bullets and
other fragments from injuring a
person.

4. Making liquid armor
The liquid is formed from a mixture of
nanoparticles, non evaporating liquid.
Kevlar and other ballistic materials are
treated with liquid armor to strengthen the
liquid when agitated.

5. How liquid armor works
“liquid armor” acts as a liquid under normal
conditions, but when a particle impacts the
liquid suddenly it tenses which will not let
particles to penetrate the surface.
This new material has been tested to stop bullet
and sharp objects at a close range.
When an object strikes the liquid, the impact is
distributed over a large area causing the object
to slowdown.
