Firexx conducted its first instrumented
testes in 1993 on Firexx Fortification at the Battelle
Laboratory in Ohio. In that test, Firexx was proven to reduce
overpressures by 98%. However, since the test involved a very
small charge and point blank detonation, scientifically scalable
testing without those anomalies was required.
A test was conducted jointly by Firexx and
Saudi Chemical Company in 1997. A charge equivalent to 25 lbs of
TNT detonated at 1 foot distance from a Firexx Fortification
barrier wall consisting of just a few inches of Firexx cladding.
With the wall off set from the target 6-in standard concrete
block wall by just two ft, the target wall was undamaged by the
blast. A later test in Saudi Arabia involved the explosion of 25
lbs of TNT at just 4 feet. The 6-in concrete block wall
protected by a few inches of Firexx remained undamaged, while an
unprotected wall subject to the same detonation was breached
with a 4 ft diameter hole and debris was scattered more than 200
ft from the target.
Firexx Fortification's blast attenuation
capability was again dramatically validated at the U.S. Force
Protection Equipment Demonstration I and FPED II at Quantico
Marine Base in Virginia in 1997 and 1999. A test involved 25 lb
of Pentolite detonated at 15 feet distance between two 6 in
thick concrete wall structures. The unprotected wall was
completely destroyed, while the wall protected by just a 6-in
Firexx Fortification padding was totally undamaged.
In 1997 Firexx conducted additional
instrumented tests at Aberdeen Proving Ground in Maryland, In
one of experiments, 45 lbs of Pentolite (= ~ 50 lbs TNT) was
detonated at a distance of ~ 10 feet. The conclusion by
Aberdeen's scientists was that the 8-in depth Firexx
Fortification pad had reduced overpressure "bleed through"
(roughly defined as the pressure remaining at the back of the
pad) by up to 94%.
Firexx continues to engage in testing of
Firexx Fortification. Each test reaffirms the conclusion of
Firexx engineers that the material has remarkable blast
attenuation qualities that can be designed as scalable and
efficient protection against almost any conventional threat
