Abstract

This research proposes using a hybrid core consisting of foam metal and a ceramic tile to enhance the impact resistance of the sandwich construction. We assess the impact response of such an enhanced sandwich under a low-velocity drop-hammer load. Two thicknesses and three positions of the ceramic tile were considered. The low-velocity impact experiment was performed with a 16 mm hemispherical hammerhead and an impact energy range of 30–70 J. The results indicate that the ceramic tile significantly increases the impact resistance of the sandwich. A sandwich with a ceramic tile in the middle of the aluminum foam core had the highest peak force, perforation resistance, and energy absorption. Moreover, the performance was better for the thicker ceramic tiles, and the different damage patterns of the post-mortem sandwiches were analyzed. The underlying mechanisms of enhanced performance are discussed schematically in detail for the sandwiches. These results indeed showed that this proposed sandwich construction could be considered as a potential candidate in high-performance protective component.

瓷砖增强泡沫铝芯夹层的冲击响应实验研究

本研究提出采用由泡沫金属和瓷砖组成的混合芯材来提高夹层结构的抗冲击性。我们评估了这种增强型夹层在低速落锤载荷下的冲击响应。考虑了瓷砖的两种厚度和三种位置。采用16 mm半球形锤头进行低速冲击试验，冲击能量范围为30 ~ 70 J.结果表明，瓷砖显著提高了夹层的抗冲击性。在泡沫铝芯中间放置瓷砖的夹层具有最高的峰值力、穿孔阻力和能量吸收。此外，越厚的瓷砖性能越好，并对夹层的不同损伤模式进行了分析。对三明治性能增强的基本机制进行了详细的图解讨论。这些结果确实表明，这种三明治结构可以被认为是高性能保护元件的潜在候选。
