Double-Doubles introduce an alternative approach to design composite laminate structures with a proper and effective optimization in terms of laminate thickness and plies orientation. A Double-Double design for a composite stiffened panel has been proposed and optimized to meet the material strength requirements, resulting in a total mass reduction up to 26.48% as compared to the starting design.
