Can you give me some real-world airframe examples where every lamina in a laminate (via the conductive fibres) is effectively electrically bonded to adjacent structure ? Open question.
Guess I didn't make myself clear- my point was that UNLESS one could reasonably figure out HOW to ground both ends of a ' layer' of prepreg tape, the issue of continuity of a fiber layer was of no consequence re LIGHTNING STRIKE. I was not talking about structural issues.

I am not aware of any airframe that even tries to accomplish that re lightning protection. As to various methods eg imbedded mesh, foil, metal paths, conductive paint AFIK they all have their place. In some cases, re the protection of penetrations of composite structures by metal things like pumps, structure fittings, etc, copper plating on both sides and ' hole' of the penetration does work but is normally too expensive - complex to do for commercial production.
