Researchers at Rensselaer Polytechnic Institute have come up with a way to detect potential structural problems with fighter planes while in flight, and in some cases repair them.
The technique, which is still experimental, involves applying an epoxy later infused with a wire grid and carbon nanotubes onto a wing or other structure. The epoxy is similar to the materials currently used to make fighter plane components. The wire grid and the nanotubes function as a communication network. Mechanics (or a computer) will shoot an electrical charge through the structure and measure how long it takes an electrical charge to … Read more
