Abstract：The porous metal fiber material is a kind of composite structural and functional integrated material
which has been widely concerned and studied in recent years. It has good electrical conductivity, thermal conduc‐
tivity hole shape stability, processing, welding, dust capacity and other advantages. In this paper, the preparation
methods of porous metal fiber materials were reviewed. The application and research status of stainless steel, ti‐
taniμm and titaniμm alloy metal fiber porous materials in the fields of filtration separation, sound absorption and
noise reduction, biomedicine and hydrogen energy devices were introduced
