Since the composites are inherently non-conductive, lightning damage prevention systems are incorporated into them... i.e. They run wire in the matrix during the fabrication process. For design details you'd have to chat with the Boeing designers... Good luck... ;-)

I can do that, my roommate’s old fiance works there, has a PhD in aerospace engineering. She was really big in composites too, I think I will search her out and ask her.

Not all composites are nonconductive. Carbon is conductive.

Not sure about what Boeing is doing with the 787, but embedding conductive wire mesh is in the structual laminate to dissapate static charge is common practice in several composite homebuilts I'm aware of. Most notably, the Lancair, has been using this technique for about 10 years after some rather catastrophic failures after lighting strikes in flight.
