Investigation on the impact resistance of 3D printed nacre-like composites

3D-Printed Biomimetic Hierarchical Nacre Architecture: Fracture Behavior and Analysis

“…The high stiffness, toughness, and strength of these nature-inspired materials could be readily applied, such as in the leading edge of aircraft foils, or protective layers in turbine blades, to locally diminish abrasion, damage by impact, and surface wear in these vital structural applications. On the other hand, the chemistry between organic and inorganic region could be altered to generate resorbable and osteoinductive hierarchical materials for application in regeneration of bone. , This experiment focused on ballistic performance to characterize nacre composite using the following parameters crucial in determining the impact energy absorption . Consequently, the absorbed impact energy by the fabricated Nacre-like structure “ e ” can be mathematically formulated by a function of the dimensional parameters as, e = f ( A M , A B , v i , D i , m i , ρ c , E c , σ y c , I c ) where A M and A B represent the areas of mortar and brick, respectively, ρ c Is the density of the composite, E c and σ yc are the composite’s elastic modulus and yield strength, and I c describes the Izod strength of the composite.…”

“…42 Ko et al designed the nacre-mimicked architecture to fabricate an optimum impact resistance under three various impact conditions through an integrative utilization of bi-material 3D printing, drop-weight impact test, parametric study, and FEA. 43 3D printed materials are not limited to static nature but can be reformed by shifting distinct characteristics, such as shape, hardness, color, functions, and transparency, when subjected to heat, magnetic or electrical source, water, pH, and light, which is an advance form of 3D printing known as 4D printing 44,45 (Figure 2a). 3D-and 4D-printed composites cover vital applications in mechanical constructions, in aeronautical, automotive, consumer goods, and aviation industries, and in sports or safety equipment.…”
