Mechanical Properties of a Honeycomb Structure Dispersed with 3D-Printed Fe₃O₄ Nanomaterials

The honeycomb structure demonstrates exceptional stability, efficient mechanical performance, outstanding load-bearing capacity, and energy-saving and lightweight properties, rendering it extensively employed in various fields such as industrial manufacturing, radiation protection building, aerospace engineering, and wave-absorbing stealth materials. Bionic design can enhance the performance of structures, making bionic honeycomb design valuable in engineering. This study employs a bionic optimization design based on the original honeycomb size to investigate the impact of a new composite honeycomb core structure on mechanical properties. Orthogonal experiments are conducted to explore the effect of honeycomb size on mechanical properties and determine the optimal size. Combining numerical simulation and 3D printing experiments, we examine the mechanical properties of both nano-Fe3O4 particle-distributed honeycomb structure and common structures, analyzing mechanisms behind their tensile and compressive properties.
