I have been rivited by your postings on Rotorheads re bonding. Having built a boat in the mid 80's using fast curing epoxies, and recently a kit plane from OZ using a much slower curing epoxy LC3600, just about to fly, I found this modern material much better to work with. The heat build up appeared much lower.

However my question is whether you have any theories on carbon fibre composites and how they would be affected by electrostatic discharges.
There was a helecopter crash about 10yrs ago where the tail rotor failed, it was made of composites. It passed the required strength tests, in fact was stronger than the original metal part, but appeared to fail after a strong lightning discharge past through it.
