Abstract
Composite stiffened panels are primary structures in aircraft.The design of the composite stacking sequence can improve the strength of the panels, but it will also affect the curing deformation.Therefore, the stacking sequence design of composite panels must consider both strength and curing deformation.In this study, the simulation models of the failure and the curing deformation of the composite panels are established.Based on the design of experiment method, NSGA-II genetic algorithm and the simulation models, a stacking sequence optimization method which considers strength and curing deformation simultaneously is developed for the composite stiffened panels.It is found that the developed optimization method could improve the strength and significantly reduce the curing deformation.
