Porous material comprising a plurality of intersecting cut carbon fibers each having a diameter of 3 to 20 microns, the fibers being covered with a thin metal film and being substantially completely and randomly dispersed, accumulated and bound with a binder at portions of the intersections of the fibers, to form a porous structure through which a plurality of pores extend continuously from one surface of the material to the other.

A porous carbon fiber material comprising a multiplicity of cut carbon fibers having a diameter of 3 to 20 microns, said fibers being substantially completely and randomly dispersed with the fibers overlaid and intersecting each other, a binder contacting said fibers at their points of intersection

A porous carbon fiber material comprising a multiplicity of cut carbon fibers having a diameter of 3 to 20 microns, said fibers being substantially completely and randomly dispersed with the fibers overlaid and intersecting each other, a binder contacting said fibers at their points of intersection to form a porous structure including a multiplicity of pores which extend continuously from one surface of said material to the other, said binders being selected from the group consisting of phenolic resin, epoxY resin, furan resin, xylenol-formaldehyde resin, urea resin, melamine resin, aniline-formaldehyde resin, Friedel-Crafts resin, unsaturated polyester resin, polyvinylalcohol, polyacrylic resin, polyvinylbutyral, polyvinylpyrrolidone, polyvinylacetate, polystyrene and polyisobutylene, and a thin metal film covering each of said fibers.
