摘要: 复合材料夹芯板由薄而硬的蒙皮和多样化的夹芯构成,作为一种轻量化结构,具有高比强度、高比刚度的特点,在准静态和动态载荷下具有优良的承载能力和耐撞性能。但是,复合材料夹芯板在工程应用中容易受到外来物冲击,特别是受到低速冲击后,其表面虽无明显损伤迹象但结构内部可能受损严重。本文介绍了复合材料夹芯板的结构及近年来夹芯板的芯部结构设计,重点归纳不同复合材料夹芯结构低速冲击下的力学性能,并总结相应夹芯板的失效形式。基于国内外研究现状,展望了未来复合材料夹芯板的重点研究方向。

Abstract: Sandwich structure is mainly used as lightweight structures for various engineering and structural applications, which consists of thin and hard skin and diversified core structures. It is highlighted that composite sandwich panel can provide excellent bearing capacity and crashworthiness characteristics under quasi-static and dynamic loadings. However, the composite sandwich panel is easy to be impacted by foreign materials in engineering application. Especially after being impacted under low-velocity impact, the internal structure may be damaged seriously although there is no obvious damage sign on the surface. The structure of composite sandwich panel and the core structure designs of sandwich panel in recent years are briefly reviewed, and the mechanical properties of different composite sandwich structures under low velocity impact are summarized. In addition, the damage behavior of sandwich panels with corresponding core design is discussed. Based on the research status at home and abroad, the suggestions for the research possible direction of the composite sandwich structure in future are forecasted.

Key words: sandwich structure, core design, low-velocity impact, composite
