Abstract

Based on the microstructure of the cross section of the beetle elytra, a kind of bio-inspired lightweight structure with fibre-winding pattern was designed and made by the carbon fibre material. The mechanical and thermal properties of the lightweight structure were studied with finite element method. At the same time, the quasi-static compression experiment was carried out. The experimental result and the finite element analysis result were compared and analysed, which proved the effectiveness of the finite element analysis. Additionally, the mechanical properties of two kinds of structure units with the different fibre winding pattern were analysed and compared, the result showed the structure with two layers of different fibre-winding patterns was better to improve its mechanical performance. Also, thermal characteristics of the structure showed its thermal protection property was favorable.
