ABSTRACT:
A shaped article having EMI shielding properties, having been shaped by thermoforming of a planar sheet, and having a shape requiring the planar sheet to exhibit a stretch ratio of at least about 300%, and up to about 500%. The article consists essentially of a fibrous metal mat substantially surrounded by a fiber-coat and a polymeric carrier for support of the mat. The fiber mat may also be embedded into the carrier material. The fiber-coat may be sprayed onto the mat or, as a thermoplastic material, may be forced together with the metal fiber mat to surround it, and such procedure may take place before or after attachment to the carrier material.
