Abstract

A method for the production of a fibrous metal structure by weaving with metal weft yarns and metal warp yarns. The method includes weaving the fibrous structure by successive weaving of metal clasps that are used as weft yarns. For the purpose of weaving, each of the arms of each of the metal clasps is introduced into at least one shed, each shed being formed by two warp yarns.

First claim

The invention claimed is:

1. A method of production of a three-dimensional fibrous metal structure by weaving with metal weft threads and metal warp threads, the method comprising:
producing a plurality of metal clasps by bending metal segments, each of said metal clasps including a first arm extending along a first direction and a second arm extending along a second direction that is different from the first direction, the first arm and the second arm connected to one another by a joining element, and
after said producing, weaving in three dimensions by successive weaving of the plurality of separate metal clasps acting as weft threads, said weaving being carried out into a first weaving plane formed by a plurality of the first arms successively positioned one next to another and a separate second weaving plane formed by a plurality of the second arms successively positioned one next to another by the introduction of each first arm and each second arm of each of said metal clasps into at least one shed, each shed being formed by two warp threads.

2. The method of production according to claim 1 , wherein the metal segments are of rectilinear shape.

3. The method of production according to claim 2 , wherein, prior to said bending, said method comprises cutting a plurality of metal segments.

4. The method of production according to claim 2 , wherein said metal clasps are bent during said bending into a U-shape and/or a V-shape.

5. A fibrous structure produced by the method of production according to claim 1 , wherein said fibrous structure is formed by a plurality of woven warp threads and a plurality of woven weft threads, the weft threads being formed by preformed metal clasps.

6. The fibrous structure according to claim 5 , wherein said plurality of warp threads and said plurality of weft threads are metal threads based on titanium and/or SiC-titanium threads and/or SiC-boron threads and/or SiC—SiC threads.
