In orthopedic implant development, incorporating a porous structure into implants can reduce the elastic modulus to prevent stress shielding but may compromise yield strength, risking prosthesis fracture. Bamboo’s natural structure, with its exceptional strength-to-weight ratio, serves as inspiration. This study explores biomimicry using bamboo-inspired porous scaffolds (BISs) resembling cortical bone, assessing their mechanical properties and fluid characteristics. The BIS consists of two 2D units controlled by structural parameters α and β. The mechanical properties, failure mechanisms, energy absorption, and predictive performance are investigated. BIS exhibits mechanical properties equivalent to those of natural bone. Specifically, α at 4/3 and β at 2/3 yield superior mechanical properties, and the destruction mechanism occurs layer by layer. Besides, the Gibson–Ashby models with different parameters are established to predict mechanical properties. Fluid dynamics analysis reveals two high-flow channels in BISs, enhancing nutrient delivery through high-flow channels and promoting cell adhesion and proliferation in low-flow regions. For wall shear stress below 30 mPa (ideal for cell growth), α at 4/3 achieves the highest percentage (99.04%), and β at 2/3 achieves 98.46%. Permeability in all structural parameters surpasses that of human bone. Enhanced performance of orthopedic implants through a bionic approach that enables the creation of pore structures suitable for implants.

“…Different methods have challenged tensile strength, [ 7 ] compressive strength, and energy absorption, [ 8 ] to classify these materials as candidates for applications such as a core for sandwich panels. [ 9,10 ] These researches were followed by experiments such as Feshat et al [ 5 ] which used polyurethane foam as a precursor and electrodeposition method as the production method. They targeted lithium battery applications of these foams and investigated the mechanical behavior of nickel foams through simulation.…”

This investigation aims to assess the mechanical behavior and energy absorption properties of the light sandwich panels made of open‐cell polymer and nickel/polymer foam. A portion of the ultralightweight foam sandwich panels (14.23 g) is produced by 3D printing and electrodeposition methods with 35, 45, and 55 seeds numbers, which lead to 4, 5, and 6 pores per inch (PPI); then a uniaxial compression test is applied to measure maximum compressive strength, strength‐to‐weight ratio, energy absorption density, efficiency, and complementary energy. The results indicate that compared with typical open‐cell nickel foams and polymer precursors when the thickness of the nickel layer is about 50 micrometers, the aforementioned properties of the sandwich panel shows a significant improvement. Improvement of properties changes by increasing PPI and CAD seed numbers. In a nickel/polymer sandwich panel with 6 PPI, the first maximum compressive strength, specific energy absorption, and energy absorption efficiency reach 0.93 (MPa), 0.93 (J.boldg−1), and 60%, respectively. 3D‐RP‐Ni‐6 improves 3D‐RP‐6 first maximum compressive strength and specific energy absorption by six times and two times, respectively. These significant improvements in the properties of these sandwich panels make these advanced materials a suitable candidate for the high strength applications.

Metal foams are one of the unique materials that need more attention in terms of mechanical and microstructural characterizations. In the present study, different kinds of metal foams such as Ni, Cu, and a novel type of multi‐layered metal foams with Ni‐Cu and Cu‐Ni coating layer orders have produced and characterized in terms of mechanical response and microstructure of these novel materials during a uniaxial compression test. These multi‐layered metallic foams have a strong mechanical adhesion at the interface due to the nature of electroforming process and the effect of solid solution area at these interfaces. Besides, Multi‐layered metal foams are superior to Ni and Cu pure metal foams in terms of mechanical response, applying a multi‐layered metallic coat with 60 and 69 μm diameter for Ni and Cu improved the yield point of the Ni and Cu single layer metallic foams for 3 and 7 times, respectively. Moreover, in terms of energy absorption density, the multi‐layered metallic shell has improved the energy absorption density for 3 and 5.5 times compared to Ni and Cu metal foams, respectively. This study shows that applying multi layered coatings to metal foams with Ni as the first layer has superior characteristics compared to single layer metal foams.This article is protected by copyright.
