    Abstract:

    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.
