Maybe we need to start a new thread because this is getting off the subject... other proprietary processes are useless.

Bonded Repairs
Thanks for a most cogent explanation and one of the best contributions to general knowledge I've ever read, here or anywhere else.
Anyone who has tried to patch a hull breach in a jetski or similar composite hull can attest to the fact that you can do the same exact technique on two different parts of the hull and achieve 2 different levels of success, because of the different levels of demand on the patches and the difference in what each part of the hull was exposed to in normal use.
We've had centuries of experience with sheet metal but very little by comparison dealing with composite layups.
It's going to be very interesting to see how Boeing's 7L7 fuse barrels behave initially, and how some of ABI's composite panels - in service for years - look after a couple decades of commercial (don't give a s**t) use.
One can expect "learning situations" as we gain the same level of intuitive knowledge for composites that we already have for sheet metal.
And kudos to all the other contributors here - this is one of the least acrimonious threads I've ever read on pprune, and perhaps one of the most important.
