This study focuses on integrating lightweight additive-manufactured honeycomb sandwiches (AMHS) for ship structures. AMHS panels are valued for their superior strength-to-weight ratio, corrosion resistance, and thermal insulation, contributing to more efficient shipbuilding by lowering weight without sacrificing durability. Weight reduction results in reduced ship fuel consumption and improved performance. The study explicitly analyses the delamination characteristics of these panels through three-point bending tests on composite honeycomb sandwich specimens created via additive manufacturing. A mathematical model was developed to correlate experimental results with the ultimate strength and delamination of AMHS. The study examines the failure mechanisms under bending loads. It employs non-linear strength analysis to understand the buckling behaviour and macro-delamination at the interfaces and analyses the impact of the honeycomb cell size. As stress increases, the buckling zone enlarges and triggers delamination once a critical stress threshold is surpassed. Ultimately, the research provides insights into the potential of AMHS as a lightweight alternative to traditional steel components in maritime applications.
