Re amicus's interesting:
Just remember that both Boeing and the FAA in their (lack of) wisdom did not put any internal insulation on upper half of 787,a dangerous FST failure point that I debated long and hard with the FAA and lost. The self ignition temperature of Toray 3900-2 epoxy on 787 is around only 580 degrees F vs 2000 degree F for a decent aluminum, so it doesn't take much. Plus copious amounts of toxic FST released inside the aircraft
I have just found
Paper re FST / CF/Expoxies and 787/A350 which I shall try to digest
NoD
PS Amicus... jumping ahead, can you give a precis as this FST aspect, and maybe relate to a recent widebody crash in N America where an external fire burnt through and into the Pax Cabin, but only after the Pax had been able to escape?
