Abstract: This research explores nature-inspired designs for materials with high impact resistance, utilizing 3D printing techniques. The study focuses on a layered composite design, combining a nacre-like outer layer with a core resembling tubulane. The solid fill in the outer layers, like dense aragonite in natural nacre, and the tubulane-like core significantly enhance energy dissipation. This customizable design, made possible by 3D printing, is tested for ballistic impact resistance. The effectiveness of the composite is assessed using a 40-grain lead-tipped .22 LR bullet at an initial velocity of 330.7 m/s. A specialized chronograph setup measures the initial and post-penetration bullet velocities to quantify energy absorption. The study offers valuable applications in aviation, structural design, and personal safety gear, pushing the boundaries of material science and additive manufacturing for public safety.
