Using Nanotubes to Detect and Repair Cracks in Aircraft Wings, Other Structures
September 27, 2007
Researchers at Rensselaer Polytechnic Institute have developed a simple new technique for identifying and repairing small, potentially dangerous cracks in high-performance aircraft wings and many other structures made from polymer composites. Once a crack is located, engineers can use a simple new method to seal the crack, with a 70 percent recovery in strength.
