Abstract

A sintered metal fiber medium according to the present invention comprises metal fibers and a porous metal structure, which porous metal structure has two surfaces. The fibers are present on only one of the surfaces, providing, the fibers are present in at least part of the pores of the porous metal structure. A method for manufacturing a sintered metal fiber medium from metal fibers and a porous metal structure having a first surface and a second surface according to the present invention, comprises the steps of • making a primary slurry comprising metal fibers, a solvent and a binding agent by mixing the metal fibers and the binding agent; • applying the primary slurry on either the first surface or the second surface of the porous metal structure; • solidifying the primary slurry by removing the solvent yielding a composite structure comprising the metal fibers, the binging agent and the porous metal structure; • debinding the binging agent and sintering the composite structure.
