Abstract: The invention relates to a fabric comprising carbon threads, said fabric having a mass per unit area within the range of 40 g/m2 to 100 g/m2, preferably from 40 g/m2 to 80 g/m2, specifically from 60 g/m2 to 80 g/m2, and characterized in that it comprises staple fibers, said staple fibers extending out from the threads constituting the fabric from which they originate and extending in a direction that is not parallel to the direction of the thread from which they originate and/or in that the fabric is needled. The invention also relates to the use of this fabric in a diffusion layer for a fuel cell and a method for manufacturing this diffusion layer.

Abstract: The weaving loom of the present disclosure includes a warp thread supply system, a frame type warp thread sequencing system, a reed and a weft thread insertion system. The present disclosure also provides a weaving method using the weaving loom. The method includes: a step of designing a flat fabric which are multilayered and presenting several adjacent sections in a weft direction whose weave and layout are different; a step of designing a set of side-by-side frames for enabling a weaving of the adjacent sections in a continuity of a weft according to designed weaves and layouts; and a step of carrying out the weaving.

Abstract: A weaving loom includes a system for inserting weft threads in a plurality of layers and a system for inserting and sequencing warp threads in such a way as to produce a multilayer fabric having a defined weave. It includes at least two feed systems of which the speed and traction force are controlled such that, at least locally, one portion of the layers of fabric is driven by the feed mechanism of same at a different speed to at least one other portion of the layers of multilayer fabric so as to produce at least one aperture on the multilayer fabric.
