Composite materials are used in aerospace design because of their high strength-to-weight ratio. On modern airplanes, composite wings offer a greater degree of aerodynamic efficiency due to weight savings but at the same time introduce more structural flexibility than their aluminum counterparts. Under off-design flight conditions, changes in the wing shape due to structural flexibility cause the wing aerodynamics to be non-optimal. This effect could offset any weight-saving benefits realized by the composite wings. Structural flexibility could also cause adverse interactions with flight control and structural vibration that can compromise aircraft stability, pilot handling qualities, and passenger ride quality.
