Herein, the mechanical properties of closed‐cell aluminum foam‐polyurethane composites (AF‐PU composites) under cyclic compression are studied experimentally. The results show that AF‐PU composites with PU coating at the bottom exhibit great deformation recovery ability and excellent reversible energy dissipation capacity, which is mainly associated with the presence of PU coating at the bottom. The high stiffness of AF‐PU composites is also possessed. The reversible energy dissipation of AF‐PU composites with PU coating at the bottom is primarily caused by the recoverable extrusion of PU coating at the bottom. Also, AF‐PU composites with PU coating at the bottom indicate an excellent low cycle fatigue performance, which verifies the reliability of AF‐PU composites with PU coating at the bottom utilized for repetitive energy dissipation applications. The results presented herein are conducive to broadening the scope of the application of closed‐cell AF.

循环压缩下闭孔泡沫铝-聚氨酯复合材料的表征

在此，通过实验研究了闭孔铝泡沫-聚氨酯复合材料（AF-PU复合材料）在循环压缩下的力学性能。结果表明，底部带有PU涂层的AF‐PU复合材料具有出色的变形恢复能力和出色的可逆能量耗散能力，这主要与底部存在PU涂层有关。还具有AF-PU复合材料的高刚度。底部带有PU涂层的AF-PU复合材料的可逆能量耗散主要是由于底部PU涂层的可回收挤压引起的。此外，底部带有PU涂层的AF‐PU复合材料还具有出色的低周疲劳性能，验证了底部有PU涂层的AF‐PU复合材料的可靠性，该材料可用于重复的能量消散应用。本文介绍的结果有助于扩大闭孔AF的应用范围。
