Thanks Brian
I'll read the document to see if they actually address the issue of bond durability as well. The FAA lump composites and adhesive bonded structure in the same bucket. It is important that they specifically call out bond durability tests, because if they rely just on damage tolerance, static strength and fatigue testing then they are wasting their time. It is possible to manufacture a bonded structure which is designed to be damage tolerant and which meets static and fatigue requirements, but still disbonds in service.
