Composite corrugated sandwich structures have a wide range of applications in aerospace field, and the loss of structural load carrying capacity due to low-velocity impact damage has become one of the main threats in practical applications. In this study, the impact resistance of corrugated sandwich panels prepared from thermoplastic composites (TPC) under low-velocity impact loading was investigated. Through a series of drop-weight experiments and finite element simulations, the impact response process and damage morphology of the thermoplastic composite sandwich panels were obtained, and the effects of different impact energy and different core arrangements on the energy absorption performance of the structure were explored. Finally, a parametric analysis of the perpendicularly-arranged double-layered corrugated sandwich panel was carried out. The results show that thermoplastic composite sandwich panels exhibit an overall collapse response rather than localised damage, and the structure maintains good integrity and stability. The perpendicularly-arranged sandwich panels rely on the orthogonal configuration characteristics to provide optimum impact load carrying capacity, their impact resistance can be further improved by increasing the thickness of top face-sheet and reducing the thickness of the middle face-sheet at the same time. This provides a basis for promoting the application of TPC in engineering and the design of sandwich structures.

复合波纹夹芯结构在航空航天领域有着广泛的应用，由于低速冲击损伤导致结构承载能力的丧失已成为实际应用中的主要威胁之一。在这项研究中，研究了由热塑性复合材料 (TPC) 制备的波纹夹芯板在低速冲击载荷下的抗冲击性。通过一系列落锤实验和有限元模拟，获得了热塑性复合夹芯板的冲击响应过程和损伤形态，探讨了不同冲击能量和不同芯材排列方式对结构吸能性能的影响。 . 最后，对垂直排列的双层波纹夹芯板进行了参数分析。结果表明，热塑性复合夹芯板表现出整体坍塌响应而不是局部损坏，并且结构保持良好的完整性和稳定性。垂直布置的夹芯板依靠正交配置特性来提供最佳的冲击承载能力，其抗冲击性可以通过增加顶部面板的厚度和同时减小中间面板的厚度来进一步提高. 这为促进TPC在工程中的应用和夹层结构的设计提供了依据。垂直布置的夹芯板依靠正交配置特性来提供最佳的冲击承载能力，其抗冲击性可以通过增加顶部面板的厚度和同时减小中间面板的厚度来进一步提高. 这为促进TPC在工程中的应用和夹层结构的设计提供了依据。垂直布置的夹芯板依靠正交配置特性来提供最佳的冲击承载能力，其抗冲击性可以通过增加顶部面板的厚度和同时减小中间面板的厚度来进一步提高. 这为促进TPC在工程中的应用和夹层结构的设计提供了依据。
