随机（泡沫）多孔金属的多功能性能现在已经有了很好的记录。这篇文章比较了这种材料与具有周期性细胞的材料的预计能力，配置为面板，管和壳的核心。实施的机会是作为超轻结构，紧凑的冷却，在能量吸收和振动控制。周期性拓扑结构包括微桁架晶格或棱柱材料。性能的好处，可以预期在实施这些定期材料，并与竞争的概念进行比较。制造这些材料的方法进行了讨论，并解决了一些成本/性能的权衡。(C)2001爱思唯尔科技有限公司版权所有。
The multifunctional performance of stochastic (foamed) cellular metals is now well documented. This article compares such materials with the projected capabilities of materials with periodic cells, configured as cores of panels, tubes and shells. The implementation opportunities are as ultra-light structures, for compact cooling, in energy absorption and vibration control. The periodic topologies comprise either micro-truss lattices or prismatic materials. Performance benefits that can be expected upon implementing these periodic materials are presented and compared with competing concepts. Methods for manufacturing these materials are discussed and some cost/performance trade-offs are addressed. (C) 2001 Elsevier Science Ltd. All rights reserved.
