This study examines the mechanical performance of bio- and bio-inspired composite sandwich panels under out-of-plane compressive loading. Using balsa wood face sheets natural oak tree cupules for core reinforcement, research aims to develop lightweight, sustainable structures. Three different cupule arrangements geometries were tested, with without polyurethane (PU) foam infill, compare commercial cores. The results show that geometry significantly influences behaviour, demonstrating notable load-bearing energy absorption capabilities, though a tendency towards brittle fracture. Reinforcement techniques, such as duplication integration PU foam, explored enhance capacity while mitigating sudden failure. Panels reinforced cupule-filled cores exhibited superior properties compared non-reinforced highlights potential using improve sustainability in panel design. Furthermore, structures fabricated via Multi Jet Fusion additive manufacturing, harnessing unique achieve printed structures, emphasising their structural engineering applications.
