Abstract
Some embodiments are directed to a method and a device that allows fragile fibers, such as carbon fibers, for example, to be recycled so that they can be reused in a new form.
Claims16
A method for unweaving and realigning carbon fibers, from offcuts of fabric having warp and weft yarns, the method comprising:
- unweaving the fibers using combs including teeth;
- realigning the fibers by successive contacts with at least two walls of a first alignment module, that includes at least two deflectors made up of planes that are inclined with respect to the vertical by a respective angle α and β such that 90°≤α≤0 and 90°≥β≥0, the alignment module having an opening in the lower part;
- and
- shaping by a second module.

A device, comprising:
- an unweaving tool that includes two grids, the two grids including a first grid, and a second grid;
- a first alignment module arranged under the two grids;
- and
- a second module positioned downstream of the first module;
- wherein the first alignment module has at least two deflectors made up of planes that are inclined with respect to the vertical by a respective angle α and β such that 90°≤α≤0 and 90°≥β≥β0, the alignment module having an opening in the lower part.
