Stiffened composite panels are often adopted for structural components of aircraft to avoid the buckling. It is well known that stacking sequence optimizations are indispensable for the laminated composite structures. For the stiffened composite panels, they usually have two sets of stacking sequences because they consist of a panel skin and a stiffener laminate. This causes that the two sets of the stacking sequence should be optimized at the same time in the structural optimizations for the stiffened composite panels. Authors have proposed a new stacking sequence optimization method. That is improved fractal branch and bound method to optimize the multiple stacking sequences. This method is applied to obtain two optimal stacking sequences for a maximization of buckling load of a blade-stiffened composite panel. As a result, its high validity is confirmed.
