Abstract Mechanical properties and microstructure of the bovine hoof wall have been studied. The reduced modulus and hardness of the transverse and the longitudinal specimens decrease from the outside to the inside, and reach a peak of 4.69 GPa and 0.15 GPa, respectively. The further work reveals that the enhancement mechanism is the lamellar structure and fiber-refined mode. In addition, a kind of structural model is designed and fabricated by three-dimensional printing technology, whose performance is improved by 55%. We hope this work can provide ideas for a new high-toughness and light-weight armor design.

基于牛蹄壁的高韧性轻量化装甲结构仿生设计

摘要 研究了牛蹄壁的力学性能和微观结构。横向和纵向试样的折减模量和硬度由外向内递减,分别达到峰值 4.69 GPa 和 0.15 GPa。进一步的工作表明,增强机制是层状结构和纤维细化模式。此外,采用三维打印技术设计制作了一种结构模型,性能提高了55%。我们希望这项工作可以为新的高韧性和轻量化装甲设计提供思路。
