The determination of weight‐minimal laminate structures requires the well‐aimed employment of structural optimization. In contrast to the common parameter optimization in which the design variables fiber orientation and layer thickness are varied continuously, a layerwise topology optimization offers more flexibility. Starting from an initial laminate lay‐up with sufficient strength, the topology of each individual ply is varied by removing unnecessary material. The final design is well adapted to the local load fluxes.
