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.
[ What is claimed is:] [1.] A reinforced nonwoven metal fabric formed by:providing a mass of loose metal fibers;separating fibers from the mass to form a fiber web;lapping the fiber web into layers to form a multiple-layered web structure;needle-punching the multiple-layered web structure to interengage the fibers between the layers;providing a nonmetallic backing material; andbonding the backing material to the needle-punched multiple-layered web structure.
