中文摘要:
      本文设计两种不锈钢纤维多孔材料的铺制方法:平行铺制和直立铺制,通过控制铺制方法、长径比和烧结工艺得到具有不同孔结构的不锈钢纤维多孔材料,对具有不同孔结构的不锈钢纤维多孔材料的吸声性能进行分析,结果表明,长径比为5000的不锈钢纤维多孔材料的性价比最高;当材料厚度≤15mm时,平行铺制的纤维多孔材料较直立铺制的吸声性能好;当材料厚度>15mm时,铺制方法的影响不显著;烧结结点数量的多少对不锈钢纤维多孔材料吸声性能贡献不大。
Effect of Pore Structure on the Sound Absorption Properties of the Stainless Steel Fiber Porous Materials

英文摘要:
      Two kinds of paving method of the stainless steel fiber porous materials are designed in this paper, parallel paving and erect paving. The materials with different pore structure are obtained by controlling the paving method, the ratio of length to diameter and the sintering process. The sound absorption properties of the stainless steel fiber porous materials with different pore structure were analyzed. Results show that the cost performance of the stainless steel fiber porous material is the highest, the length and diameter ratio is 5000. When the thickness of the material is ≤15mm, the sound absorption properties of the fiber porous materials which prepared by the parallel way are better than the erect. When the thickness of the material is >15mm, the influence of paving method is not significant. The number of sintering nodes has little contribution to the sound absorption properties of the stainless steel fiber porous materials.
