In aviation, self-sealing fuel tank is a fuel tank or fuel bladder technology in wide use since World War II that prevents fuel tanks (primarily on aircraft) from leaking fuel and igniting after being damaged by enemy fire.
Self-sealing tanks have multiple layers of rubber and reinforcing fabric, one of vulcanized rubber and one of untreated natural rubber that can absorb oil and expand when wet. When a fuel tank is punctured, the fuel will seep into the layers, causing the swelling of the untreated layer, thus sealing the puncture.

Famous quotes containing the word fuel:
“It is now many years that men have resorted to the forest for fuel and the materials of the arts: the New Englander and the New Hollander, the Parisian and the Celt, the farmer and Robin Hood, Goody Blake and Harry Gill; in most parts of the world, the prince and the peasant, the scholar and the savage, equally require still a few sticks from the forest to warm them and cook their food. Neither could I do without them.”
—Henry David Thoreau (1817–1862)
