A reinforced nonwoven metal fabric is disclosed. A mass of loose metal fibers is processed through suitable textile apparatus to result in a metal fiber web, which is then lapped to form a multi-layered structure. This structure is then formed into a metal fabric via needle-punching. A suitable backing is then introduced during or after the needle-punch process, resulting in a reinforced nonwoven metal fabric having superior strength and durability.
