The University of Bristol in the United Kingdom has invented a method that allows the wing of an aircraft to repair subtle growth cracks on its own. This is a major breakthrough in aviation safety. The project started in 2008 and was inspired by human functions. When we accidentally wound, the solidified blood will solidify at the wound, and then the damage will slowly heal over time, but the self-healing wing is replacing the white blood cells with a liquid carbon healing agent. This technique is expected to Will be launched in the next five to ten years.
The team stated that in the past seven years, it has studied and solved the following issues, including reducing the overall weight of the wing while maintaining strength. After testing a variety of healing materials, they eventually chose a carbon fiber polymer.
In the experiment, the researchers left the healing agent in the sphere and allowed it to burst and release liquid carbon when it was traumatized. This liquid reacts with the wing material and then hardens and repairs the crack.
The University of Bristol stated that this self-healing process can achieve up to 100% restoration. In addition, thanks to advances in technology, we are expected to use more fuel-efficient, lighter-weight aircraft in the future, as the aircraft no longer has to carry the heavy components currently used in fixed-wing applications.
