| Abstract: | The composite sandwich structure with foldcore is a new type of structural material with light weight, high specific strength, high specific rigidity and multi-functional potential, which is connected with each other in core space. This kind of three dimensional structures can be formed by folding based on two dimensional materials. The main research achievements and characteristics of composite sandwich structure with foldcore in recent years are summarized and analyzed according to the lightweight and multi-functional requirements of aircraft structure in this paper. The configuration optimization scheme and fabrication process of the composite sandwich structure with foldcore are described. Moreover, the research status of mechanical properties and multi-function of the composite sandwich structure with foldcore are summarized, including the quasi-static mechanical properties, impact resistance, sound insulation, thermal protection, stealth performance of the structure, etc. Based on the research status, it provides suggestions for the research possible direction of the composite sandwich structure with foldcore in future. |
