Investigation of the ballistic resistance of the triply periodic minimal surface lattice-structured wing fabricated via 3D printing
Abstract
This study investigates the ballistic resistance of 3D-printed AlSi10Mg wing structures with internal triply periodic minimal surface lattices. A finite element model simulating impact by a 9mm tungsten sphere was validated experimentally. Results show unit cell geometry critically determines performance. At 20% volume fraction, the Diamond sheet exhibits the highest resistance. Optimizing the aspect ratio of a 10% volume Gyroid solid suggests a 20% increase in energy absorption, yielding a 16.9% better performance than a traditional solid wing with 20% volume, providing guidelines for lightweight UAV wing design..
