What are SAPI ballistic plates?
SAPI (Small Arms Protective Inserts) ballistic plates are made from the latest composite materials
consists of ballistic nylon spall cover, ceramic tiles, boron carbide, Kevlar
or Spectra and other reinforced plastic material.
How do SAPI ballistic plates work?
Once the bullet hits the vest, the ceramic fractures the
core of the projectile. The energy of the impact is absorbed by the tiles or
ballistic plates and the residual energy is absorbed by the backing. The
backing materials are determined by ballistic, structural and weight
requirements. Examples are Kevlar composites, fiberglass, Spectra and aluminum.
For rifle and some armor piercing rounds, manufacturers have
made innovations and uses advance armor ballistic plates using ultra-light
weight Spectra shield with ceramics. It only weighs about four pounds. These
plates are inserted into the pockets of your ballistic vest.
How are SAPI ballistic plates made?
Layers of ceramic are bonded together to a hard panel made
of multiple layers of Spectra shield. After which, these layers are then
wrapped with a special kind of fabric covering.
SAPI ballistic plates are designed to stop rounds of 7.62mm
and AK-47. As the bullet hits the plates, the hard ceramic inserted in the
pockets of the vest will then break up the bullet while the spectra shield will
absorbed the energy of the penetration. The bullets continue to break into
pieces while the spectra extract the energy of the impact and decelerating the
speed at the same time catching the fragments of the projectile. With this
process, the possible blunt force trauma that the wearer is supposed to
experience is substantially reduced.
