| 中文摘要: |
| 根据材料类型和点阵结构，对点阵夹层结构进行了分类简述，并从静态、动态力学性能上，分析了各类点阵夹层结构的优缺点。简要叙述了设计过程中，综合考虑材料、结构以及功能等影响因素，针对不同使用工况的要求，可对各影响因素进行匹配设计，以实现传热特性、电磁波屏蔽特性、声学特性等不同的功能性需求。然后介绍了复合点阵夹层结构(嵌锁组装、模具热压成形、穿插编织)和金属点阵夹层结构(冲压成形、挤压线切割、拉伸网折叠、搭接拼装、熔模铸造以及增材制造)的主要制造工艺。最后提出如何将设计因子与多目标进行匹配及优化设计，是轻质高强点阵夹层结构的重点研究方向，轻质高强点阵夹层结构将朝多材料及多结构复合方向发展，开发新的制造工艺，提高费效比，是点阵夹层结构材料需解决的问题。 |
| 英文摘要: |
| The lattice sandwich structures were classified according to the material type and lattice structure, and the advantages and disadvantages of all kinds of lattice sandwich structures were analyzed from the static and dynamic mechanical properties. It briefly described the design process, and gave comprehensive consideration to the influencing factors, such as material, structure and function. According to the need of different operating conditions, matching design was carried out on each impact factor to meet different functional requirements on heat transfer characteristics, electromagnetic shielding properties acoustic characteristics, etc. And then, the main manufacturing process of composite lattice sandwich structure (embedded lock assembly, die extrusion forming, interspersed with woven) and metal lattice sandwich structure (stamping forming, extrusion line cutting, stretching nets folding, lapping assembly, investment casting, and additive manufacturing) were introduced. Finally, it was put forward that how to match design factor with multi-objective for optimization design is the key research direction of the lattice sandwich structure of light weight and high strength. The light weight and high strength lattice sandwich structure should be developed in the direction of the multi-material and composite structure to develop new manufacturing process, improve the cost effectiveness, and solve the problem on lattice sandwich materials. |
