Abstract:

The rapid development of the next generation of aerospace technology has imposed more and more stringent requirements for such structural performance as the ultra-strong load-bearing, extreme heat-proof, ultra-precision and ultra-lightweight. Therefore, how to design and fabricate high-performance, lightweight, and ultra-precise aerospace thin-walled structures has become a common concern in the field of advanced material and structural design and manufacturing. This paper reviews the main achievements of high-performance design and manufacture of thin-walled components and their aerospace applications in recent years, focusing on the scientific issues including the mapping law between multi-scale structures and structural performance, the composed manufacturing principle of multi-material and multi-scale structures, and the interaction mechanism between material organization evolution and structural deformation. Moreover, the manufacturing process constraints in structural optimization, the influence of additive manufacturing process parameters on the structural optimization, the material-structure integrated design method of high-performance structures and its application in aerospace structures are discussed. The development prospects and applications of the material-structure integrated design and manufacturing methods of typical aerospace thin-walled structures in the future are also prospected, which can provide references for future related research and aerospace applications.

Key words: aerospace thin-walled components, structural design, material-structure integrated design, multi-scale optimization design, additive manufacturing, process constraints
