parvez discovered 2 months ago- A new technique that mimics healing processes found in nature could enable damaged aircraft to mend themselves automatically, even during a flight. As well as the obvious safety benefits, this could make it possible to design lighter aeroplanes in future, leading to fuel savings. The technique works as follows: if a tiny hole or crack appears in the aircraft (perhaps due to wear, fatigue or a stone striking the aircraft), epoxy resin 'bleeds' from embedded vessels near the hole/crack to seal it and restore structural integrity. By mixing dye into the resin, any 'self-mends' could be made to show as coloured patches that could easily be pinpointed during subsequent ground inspections, and a full repair carried out if necessary. Cool stuff!
