Get the wing to yield exactly how they want it to from aero loads, but somehow lay up the carbon so it doesn't yield unacceptably under FIA static load tests? I think that's probably ingenious.

Maybe a similar challenge in some respects to how structural engineers had to use very clever composite design to make the X-29A's forward-swept wing's leading edge curl down when the wing flexed up, lest an increase in angle of attack become self-reinforcing to the point of a stall or catastrophic wing failure.[0] These kinds of designs are frequently asymmetric and unbalanced (meaning different numbers of +/-45 plies) which can create internal stresses during curing, sometimes making them difficult to produce and extract from a mold without breaking the part or the mold and still getting the shape you want in the end.
