The first commercial use of CR-39 monomer (ADC) was to help create glass-reinforced plastic fuel tanks for the B-17 bomber aircraft in World War II, reducing the weight and increasing the range of the bomber. After the war, the Armorlite Lens Company in California is credited with manufacturing the first CR-39 eyeglass lenses in 1947.
A self-sealing fuel tank (SSFT) is a type of fuel tank, typically used in aircraft fuel tanks or fuel bladders, that prevents them from leaking fuel and igniting after being damaged. Typical self-sealing tanks have layers of rubber and reinforcing fabric, one of vulcanized rubber and one of untreated natural rubber, which can absorb fuel when ...
Bladder tanks, bag tanks or fuel cells, are reinforced rubberised bags installed in a section of aircraft structure designed to accommodate fuel. The bladder is rolled up and installed into the compartment through the fuel filler neck or access panel, and is secured by means of snap fasteners or cord and loops inside the compartment.
For many modern tanks, such the Italian Ariete, it is yet unknown which type is used. There was a general trend in the 1980s away from ceramic armour towards perforated armour, [50] but even many tanks from the 1970s like the Leopard 1A3 and A4, the French AMX 32 and AMX 40 prototypes used the latter system; the Leclerc has an improved version ...
The U.S. Army's M1 Abrams MBT with TUSK (Tank Urban Survival Kit) upgrade uses composite, reactive and slat armour. Military vehicles are commonly armoured (or armored; see spelling differences) to withstand the impact of shrapnel, bullets, shells, rockets, and missiles, protecting the personnel inside from enemy fire.
Drop tank storage aboard USS Harry S. Truman (CVN-75) The primary disadvantage with drop tanks is that they impose a drag penalty on the aircraft. External fuel tanks will also increase the moment of inertia, thereby reducing roll rates for air maneuvers. Some of the drop tank's fuel is used to overcome the added drag and weight of the tank.

The sidesaddle fuel tanks themselves were found to have a robust design highly resistant to crushing or crumpling from a side impact. Trucks equipped with these tanks met and exceeded the requirements of Federal Motor Vehicle Safety Standard No. 301. Studies showed that it would take about 4,000 side-impact crashes with such a truck to get one ...
