Status of mechanical properties of porous metal fibrous materials

摘要:

金属纤维多孔材料是一类新型轻质金属多孔材料，其力学性能是影响大规模应用的关键性能之一。本文详细论述了金属纤维多孔材料的拉伸性能、剪切性能、压缩性能和冲击性能等力学性能的研究进展，并简要叙述了应力波在多孔材料内部传播的研究现状，最后指出未来应加强金属纤维多孔材料的动态冲击性能及应力波在多孔材料内部的传播、衰减机制研究，从而进一步扩大金属纤维多孔材料的应用领域。

Abstract:

Porous metal fibrous materials is a new type of light porous metal materials and its mechanical properties is one of key performance affecting strongly its application. The paper foucused on the status of the tensile, the shear, the compressive and the impact properties of porous metal fibrous materials and the research progress on the stress wave propagating in the material was briefly discussed. In order to expand the application fields of porous metal fibrous materials, its dynamic shocking performance and the stress wave propagation and attenuation in the material should be studied systemly in the future.
