High interlaminar stresses in the vicinity of free edges of composite laminates can result in laminate failure by free‐edge delamination. In the current work it is shown in which way the interlaminar normal stress component is reduced by means of structural optimization resulting in laminate configurations with a minor risk of delamination.
