Abstract
A method and apparatus for ply blending. A desired thickness and a desired stiffness distribution for a composite structure are received. A model of the composite structure is split into a plurality of panels. Lamination parameters and a quantity of plies for each panel of the plurality of panels are determined using the desired thickness and the desired stiffness distribution for the composite structure. Ply shapes for each ply of the plurality of panels are determined using an objective function. A fiber angle is determined for each ply of the plurality of panels. Each ply of a first half of a panel of the plurality of panels has a different fiber angle value than each other ply of the first half of the panel.
