Title: Method for making a wet-layed, non-woven metal fiber sheet

Abstract: Provided by the present invention is a process for making wet-layed metal fiber nonwoven sheet. The process comprises dispersing a mixture of metal fibers, wood pulp and a fibrillated material into an aqueous dispensing fluid. The amount of metal fibers dispersed generally ranges from 60 to 80 weight percent, based on the weight of solids, with the amount of wood pulp ranging from 15 to 30 weight percent and the amount of fibrillated material ranging from about 5 to 10 weight percent. The dispersed mixture in the aqueous dispensing fluid is then applied to a screen, with the aqueous dispensing fluid being removed to thereby form a metal fiber sheet.
