摘要:: 泡沫铝作为重要的轻质多功能材料，因其高比强度、吸能减振、电磁屏蔽等优点已在各大工业领域得到了重要应用。国外对泡沫铝的工业化应用已经较为成熟，而我国泡沫铝的研究则起步相对较晚，与国外先进技术相比尚存在一定差距。概述了泡沫铝材料的综合特性和主要制备技术，以及我国在高品质泡沫铝材料成分设计与优化、发泡预制体制备工艺、发泡稳定性机理等关键技术方面的研究进展，得出了改善发泡效果与提升泡沫铝产品质量的有效措施；并对泡沫铝材料在兵器装备和航空航天领域的应用做了简要分析，最后给出了我国泡沫铝材料的发展思路，可为我国高品质泡沫铝材料技术的快速发展提供重要参考。

Abstract:: As an important lightweight multifunctional material, aluminum foam has been applied in various industrial fields because of its high specific strength, energy absorption, vibration reduction and electromagnetic shielding. The industrial application of aluminum foam in foreign countries has been relatively mature, while the research on aluminum foam in China started relatively late, and there is still a certain gap compared with foreign advanced technologies. This paper summarizes the comprehensive characteristics and main preparation technologies of aluminum foam materials, as well as the research progress in key technologies such as the composition design and optimization, the preparation technology of foam prefabrication, the mechanism of foaming stability and so on. Then, the effective measures to improve foaming effect and the quality of products are obtained. Furthermore, the application of aluminum foam materials in ordnance equipment and aerospace is briefly analyzed. Finally, the development trends of foam aluminum material in China are put forward, which can provide an important reference for the rapid development of high quality aluminum foam materials in China.
