Composite Materials And Lightning Stikes

Fri Apr 29, 2005 12:08 am

With an increasing amount of composite materials in new aircraft like the 787, A380, and to a lesser extent 777; what are the relative effects of lightning strikes on these aircraft. I assume (perhaps wrongly) that composites are poor conductors of electricity, hence more of the energy from the lightning would be absorbed by the plane (as heat) than with aluminium A/C which are obviously good conductors.

Any idea how they get around this? I'm guessing some form of aluminium conductor bars or aluminium skin for the A/C solves this issue.

Some interesting info on A/C and lightning strikes here.
