Effect of lightning strikes on Carbon Fibre (video and photos)
If you know a Boeing engineer, please pass this on. On average, every single airliner is hit by lightning once a year. Modern, metal planes are built to carry on perfectly safely even if they are struck but the very latest airliners are now being made of carbon fibre, which can be very badly damaged by lightning. So how are aeroplane designers making them safe to fly? BBC Transport Correspondent Richard Westcott was given exclusive access to the Airbus "Lightning Lab" based at Cardiff… (www.bbc.com) Más...Sort type: [Top] [Newest]
Why is this news? Is there a single commercial airliner which does't have a layer of conductive mesh within its composite layers? (With the exception of radomes of course -- and they have ribs.)
"does't" = "doesn't"
yes 787 https://www.businessinsider.com/boeing-removed-lightning-strike-safety-feature-787-dreamliner-faa-report-2019-12?fbclid=IwAR31_s5wA6O6Kmv3HmOoYykSF7mC0PYZx5VL8tYYA45fntJ0EQK00L_HnJo
Well, holy sh**. I stand corrected!
WTF is Boeing thinking (er, smoking)?

More profit?
There is a difference between graphite (pencil lead), carbon fibre (as used in fishing poles etc), and carbon fibre composites. The materials used in aerospace are composites and they are very much less conductive than conventional aircraft alloys. This means that they can generate much more heat for a given strike. They also suffer more structural changes which can weaken them. I was glad to see that Boeing and Airbus designs seemed to acknowledge this and it worries me to see it removed.
