My lead told me to torque those new composite panel fasteners to 35 inch-pounds, not foot-pounds. Saved a hangar queen from getting a crack.

Wait, is that a common mix-up with composites? I read an article last year about how over-torquing on carbon fiber structures can cause delamination you can't even see. They said the clamp load is totally different than on metal.

Exactly, people treat everything like it's steel.

Yeah, that invisible delamination is the scary part.
