作为新一代先进轻质超强韧结构材料,复合材料格栅和点阵夹芯结构受到了国内外学者的广泛关注.目前关于该类结构材料的设计制备以及相关力学性能研究已取得了大量的研究成果.然而对该类结构振动阻尼性能的研究则处于起步阶段.该文综述了纤维增强树脂基复合材料简单层合结构以及各类夹芯结构振动阻尼性能的研究现状.首先阐述其阻尼机理,然后分别概述了复合材料简单层合板的微观和宏观阻尼模型、复合材料粘弹性阻尼夹层结构和新型夹层结构的阻尼预报工作,最后总结归纳现有关于该类结构阻尼特性研究工作中已取得的成果和不足之处,并对其未来发展进行了展望.
As a new generation of advanced super-strong lightweight structural materials, composite grid and lattice sandwich structures have received extensive attention from domestic and foreign scholars. An abundant amount of research on such novel sandwich structures focused on the manufacturing techniques and mechanical properties was carried out. However, it needs to be pointed out that, the research on the vibration and damping characteristics of such sand- wich structures has just started, which is a new topic. Here a comprehensive review of the state of the research on vibration damping models was made for fiber reinforced resin matrix com- posite laminates and sandwich structures. Firstly, the related damping mechanisms were elabo- rated, and then an overview of micro- and macro-damping models for simple composite laminates, viscoelastic damping and novel sandwich structures was given. Finally, the results and shortcomings of the existing research on the vibration damping characteristics of such structures were summarized and the possible development in the future was predicated.
