固体金属泡沫材料展现出了许多不同寻常的物理及机械方面的综合性能,这使得它们在许多工程应用领域都极具吸引力。例如,当用作结构型夹芯板材的芯核时,泡沫材料能提供很高的刚性,同时材料的质量很轻。其在能量吸收装置中的应用是利用了这类材料在几乎恒定的应力下能承受较大变形的能力。 Solid metal foams exhibit many unusual combinations of physical and mechanical properties that make them attractive in many engineering applications. For example, when used as a core of a structural sandwich panel, the foam provides high rigidity while the material is lightweight. Its use in energy absorption devices takes advantage of the ability of such materials to withstand large deformations under almost constant stress.
