How good is composite when lightning strikes? Doesn't is explode or

This one is a completely open question to me. No, they don't conduct
electricity as far as I know. In the one famous case of a glider getting
hit by lightning, the lightning traveled along metal control rods. The
rods superheated the air inside the wings, blowing the glider to bits.
Obviously this is not a desirable outcome for an airliner carrying 300
people and no parachutes. I can only assume that the smart engineers
working on this stuff have figured out a way to stop this from
happening, but I have no idea at all what that way would be.

Embedded conductive layers.

Cool stuff. Thanks!
