What is Kevlar?
Kervlar is a very strong lightweight polymer which is drawn
into fibres.
The fibres can be spun and woven into
clothing.
Bullet proof vests used by the police contain Kevlar.
In equal weights it is five times as strong
as steel.
What is the Structure of Kevlar?
The picture above shows the
structure of Kevlar.
The hexagons in the polymer are made from carbon
atoms
and they keep the chain straight and
strong. The strength
is further increased by hydrogen bonding shown
in green.
