Bionic model design of aviation materials based on Coleoptera structure of dung beetle

At present, there are more than 600000 species of insects on the earth, and more than 90% of them can fly. The design of new aviation materials can be inspired by the delicate structure of insect membrane wings. In this paper, the Coleoptera of dung beetle is taken as the research object. After the Coleoptera is broken, the cross section is observed. It is found that the Coleoptera of dung beetle is composed of multi-layer fibers. Combined with previous studies, a new bionic aviation material structure model is proposed. The finite element analysis method is used for loading, and the contrast group is set for comparative analysis. The research results have significance for the development of new aviation material structure design. It has certain guiding significance.
