a ff ected when changing the plies’ orientations. Controlling the plies’ direction would minimize or maximize the in duced tensile stresses across the layers. This could lead to a change in the formations of the interlaminar cracks and voids which a ff ects the performance of the composite structures. In future work, an optimization strategy will be introduced in order to establish new techniques to obtain less tensile residual stresses and improve the performance of the automated manufactured composite structures.
