RE # 280 AND LIGHTNING STRIKES
Its not an issue to be discussed here- and its not an issue PERIOD.
777 have been flying for over a decade with composite tail fin. US Navy planes like A6(E) have had composite wings for over a decade. Airbus has used a composite fin-rudder for nearly two decades. I'm sure all have been hit by lightning at least once in several decades.
techniques include built in ' screen' into layups, sealant caps on fastener penetration of fuel tank areas, plating of tank penetrations for larger parts,, etc etc etc.
Direct damage for strike area is minimal.
Spend UR time on the boeing site for example or on industy sites looking up the magic word ' lightning strikes damage repair etc .
