摘要:

作為一種新型輕質多孔金屬材料，金屬纖維多孔材料兼具結構材料和功能材料的優點，擁有良好的導熱性、耐高溫、高孔隙率、大比表面積及孔結構可控等特點，受到人們越來越多的關注，并在生活、生產實踐中有著廣泛的應用。綜述了金屬纖維多孔材料的傳統和新型制備方法，評述了兩種方法的國內外發展現狀，分析和討論了兩種方法的優缺點；介紹了金屬纖維多孔材料在過濾分離、吸聲降噪、生物醫學、高效換熱及阻尼減震等領域的研究現狀，最后指出現存問題并對未來發展趨勢進行了展望。

Abstract:

As a new type of light-weight porous metal materials, the porous metal fiber materials have the advantages of structural materials and functional materials. They have good thermal conductivity, high-temperature resistance, high porosity, large specific surface area and controllable pore structure, and have attracted more and more attentions and have been widely applied in daily life and production practice. In this article, the traditional and new preparation methods of metal fiber porous materials are reviewed, the development status of the two methods at home and abroad is reviewed. The advantages and disadvantages of the two methods are also analyzed and discussed. The current research status of metal fiber porous materials in the fields of filtration separation, sound absorption and noise reduction, biomedicine, high-efficiency heat transfer and damping is introduced. Finally, the existing problems and prospects for future development trends are summarized.
