Sandwich structures have been increasingly used due to their high strength-to-weight ratio and bending and buckling resistance. Today, it is possible to create topology-optimised structures with complex shapes using lattice structures through Additive Manufacturing technologies, avoiding the difficulties in core­sheets adhesion in sandwich structures. In this paper, a 3D numerical model is proposed to assess the mechanical properties of hybrid lattice structures. A comparison between the overall response of a control surface of a tiltrotor aircraft with different cores for its sandwich panels will be studied. Specifically, two strut lattice cores and a conventional honeycomb lattice core are considered as options for the asymmetric sandwich panels.
