通过冷等静压烧结，研制出了一种吸能能力强、重量轻的新型材料。将化学镀镍磷合金涂层的聚合物粉末颗粒压制成颗粒，在真空中高温烧结。然后制备了含有有机材料的金属封闭多孔材料。测试了该材料的物理、力学和超声性能。这种材料的密度约为1.3-2.7g/cm~3。压缩试验表明，该材料的杨氏模量很低，其应力-应变曲线由线弹性部分、平台部分和波状部分组成。结果表明，该材料具有较高的吸能能力。该材料的杨氏模数随着烧结温度的升高和胞壁厚度的增加而增大。超声测量表明，该材料的衰减系数很大。这些结果还表明，这种金属封闭式多孔材料可以用作被动减振和吸能系统的材料。
A new material, which has a high energy-absorbing capacity and light weight, has been developed by cold isostatic pressing and sintering. Powder particles of a polymer coated with a nickel-phosphorus alloy layer using electroless plating were pressed into pellets and sintered in a vacuum at a high temperature. A metallic closed cellular material containing an organic material was then fabricated. The physical, mechanical and ultrasonic properties of this material were measured. The density of this material is about 1.3-2.7 g/cm3. The compressive tests showed that the Young’s modulus of this material is very low and the stress-strain curves of this material have a linear elastic part, a plateau part and a wavy part. These results indicate that this material has a high energy absorbing capacity. The Young’s modulus of this material increases with an increase in the sintering temperature and the thickness of the cell walls. Ultrasonic measurements showed that the attenuation coefficient of this material is very large. These results also indicate that this metallic closed cellular material can be used for the materials in passive damping and energy-absorbing systems.
