摘　　要：金属橡胶阻尼软夹芯结构材料采用等材复合制造工艺,具有基材成熟、阻尼高、刚柔并济和制造成本低等技术特点,由于其独特的金属丝编织空间网络勾连微结构,可获得优异的干摩擦阻尼耗能和热防护等优异性能,在国防和高端装备部件复杂使役工况下具有重要的应用前景。然而,金属橡胶材料及夹芯构件制备工艺和力学性能的一致性差、微结构与性能之间的映射关系不明确等关键问题阻碍了其性能优化调控和产业化应用。本文全面报道了金属橡胶材料及夹芯构件的研究进展,介绍了典型金属丝网微结构及机织工艺、宏细观本构理论预测模型、数值建模与全场测量技术、航空及相关领域工程应用案例分析等,剖析了金属橡胶阻尼软夹芯结构材料研制和热振服役过程中存在问题,并对其衍生结构材料研究和潜在应用进行了展望。Flexible sandwich structure materials with metal-rubber damping core have the advantages with stable basic wire material, high damping, combined stiffness and flexibility, low-cost production and so on. Due to the special microstructure with space woven wire mesh, they can exhibit excellent dry friction damping characteristics and thermal protective performances. It is vital for the defense and high-level components serving in complex or extreme conditions. However, the key problems including the poor consistence between fabrication technology and mechanical performance, and the unsure relationship between microstructure and performance have not been solved. This hampers the performance optimization and mass production application of flexible sandwich structure materials. In this paper, the research progress of flexible sandwich structure materials with metal-rubber damping core is comprehensively reported. The typical microstructures of metallic wire mesh, woven processes, macroscopic and mesoscopic constitutive models, numerical modelling technologies, full-field measuring technologies and some engineering applications are introduced. The manufacturing problems and thermo-vibration responses are decomposed respectively. The research prospects and potential applications on the extended structure materials are presented.
