FLAT STRUCTURE, PARTICULARLY TEXTILE, CONTAINING PRECIOUS METAL WIRE
Known textile flat structures contain precious metal wire or they are composed completely thereof. In order to achieve high flexural and tensile strength, at the same time with high flexibility of the flat structure, the precious metal wire is configured as a precious metal cord having a plurality of cords or a plurality of individual precious metal wires or a combination of cords and individual precious metal wires, which are in each case laid around one another and/or twisted around one another.
1 .- 17 . (canceled)
18 . A sheet fabric containing precious metal wire, wherein the precious metal wire is configured as a precious metal strand comprising one of (a) a plurality of cords, (b) a plurality of individual precious-metal wires, and (c) a combination of the cords and the individual precious-metal wires, which in each case (a), (b) and (c) are laid around one another and/or twisted around one another, wherein fibers selected from carbon and glass together with the precious metal strand form a flat textile composite, and wherein the flat textile composite is at least one of (d) impregnated with a polymerizable, flowable matrix material and (e) covered with a film of a polymerizable matrix material.
