Hello roofengineer, this sounded like what you were describing to me
too. Here is the info you need:

Ammunition rack for M1A1 tank
For product information, please see ISODAMP® C-1002 damping material.
Problem: The U.S. Army?s Ballistics Research Lab sought a design for
an ammunition rack for the M1A1 tank that could withstand the
detonation of one of the rack?s stored warheads without causing the
remainder to explode. By design, the M1A1 tank and, in turn, the
military personnel it carries, can survive a single warhead explosion.
Problem-solving process: To achieve the Army?s required level of
survivability, design engineers must incorporate highly
energy-absorbent materials into the ammunition rack, to mitigate
quickly?literally in a split second?extremely powerful shock waves and
prevent sympathetic detonation of adjacent warheads. Army research
engineers had developed a new rack design, for which E-A-R engineers
designed antifratricide barriers, molded from ISODAMP C-1002 highly
damped thermoplastic elastomer. The rack somewhat resembled a wine
rack, with horizontal tubes supporting each warhead.
Solution: E-A-R developed antifratricide bars comprising C-1002
material molded over steel. Depending on their placement in the rack,
the bars were either flat, flat-and-arched or round. When the bars are
bolted into place, they form a thick, super-energy-absorbent barrier
around and between the tubes.
Result: When the Army tested an eight-round prototype ammunition rack,
outfitted with C-1002 material and installed in a simulated M1A1 tank,
only the intentionally detonated warhead went off; the remaining seven
still contained unburned explosives.
Potential applications: Bumpers and crash stops for conveying systems.
Isolation mounts for pumps, fans, motors.
