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.
