In any event there has always been controversy surrounding all composite main structures.
Beech tried with their ill fated all composite Starship. They were an outstanding failure insofar as the market was concerned and if my memory serves me correctly a presurisation fuselage test article failed catastrophically without any/or the sort of warning you get with impending failure in metal.
Failure prediction in composites as far as I am aware is not an exact science, unless it has become so in recent times.
Boeing and other large manufacturers take a much more conservative approach in there use.
I dont work for Boeing or any of the others either.
I think Pandoras box has just been opened.
