In this paper a new stacking sequence optimization method for laminated composite structure will be described. Composite structure has good specific strength and used in many aerospace industries. CFRP composite has strong anisotropic material property, so optimization of stacking sequence is indispensable. On purpose to reduce FEM analysis cost, response surface will be used to estimate objective function. In many stacking sequence optimization problem, estimation by lamination parameters as variable was effective. Although when the objective function is fracture strength the estimation of the response surface is very bad. In this research a method using multiple response surfaces will be produced to improve the estimation accuracy. By simple stacking sequence optimization problem, its effectiveness will be shown.
