摘要
轻质复合材料夹芯结构由薄而强的面板和轻质多孔的芯子组成,其芯子结构的多样性推动着夹芯结构的发展。在自然界中,各类生物在长期的进化过程中形成了最适宜其生存和繁衍的生物结构,其中高强度结构启发了科研人员对夹芯结构芯子进行仿生设计。本文对水中动物、陆地动物、飞行动物以及植物果实、根茎、叶脉的仿生夹芯结构研究现状进行了综述,阐述了仿生复合材料夹芯结构芯子及拓扑结构的设计理念。介绍了复合材料仿生夹芯结构对力学性能的改进和在相关工程中的应用。最后,基于仿生复合材料夹芯结构的发展现状,提出了科学挑战,并进行了展望。
Lightweight composite sandwich structures consist of thin and strong panels and lightweight porous cores,and diversity of their core structures drives the development of sandwich structures.In nature,various types of organisms have formed the most suitable biological structure for their survival and reproduction during the long-term evolution process,in which the high-strength structure has inspired researchers to carry out biomimetic design of sandwich structure cores.In this paper,research status of biomimetic core structure of water animals,land animals,flying animals,as well as plant fruits,roots,stems,and leaf veins is reviewed,and design concepts of biomimetic composite sandwich structure cores and topologies are described.The improvement of mechanical properties of bionic composite sandwich structure and its application in related engineering are introduced.Finally,based on the current development status of bionic composite sandwich structures,scientific challenges are presented and outlook is given.
