泡沫铝因具有低密度、高比刚度、缓冲、减震等诸多优良特性而引起了人们越来越多的关注,并且逐渐在汽车、航空等领域得到广泛运用。泡沫铝复合结构是由泡沫铝芯与外层的致密金属通过各种连接方式所组成,其形状各异且具有比单纯泡沫铝更加优异的性能。综述了国内外泡沫铝及其复合结构的应用现状,讨论了其制备方法并对其发展前景进行了展望。
Due to low density, high specific stiffness, buffering, damping and many other excellent features, aluminum foam has arise more and more attention, and gradually been widely used in automotive, aerospace and other fields. Aluminum foam composite structure is made of dense foam aluminum core and an outer layer of metal through a variety of connections. It consists of different shapes and has more excellent performance than pure aluminum foam The international and domestic application status of aluminum foam and its composite structure are synthetically expounded. Its preparation method and development prospect are also discussed.
