| abstract |
The present invention relates to an impregnated web of fibrous material comprising N individual strips of fibrous material stacked and/or connected relative to each other, wherein the N strips are adhered to each other and may at least partially overlap. According to the invention, the tape of fibrous material comprises continuous fibers impregnated with at least one thermoplastic polymer and optionally a chain extender. The web is characterized in that it has a surface S in a cross-section perpendicular to the axis of the fibers, which surface is substantially equal to the sum of the surfaces of each initial individual strip in a cross-section perpendicular to the axis of the fibers, representing is S th , S th is equal to N xl x Ep, where l represents the average width of the strip and Ep represents the average thickness of the strip, N is between 2 and 2000, and the average thickness of each individual strip is less than or equal to 150 μm, preferably Less than or equal to 100 μm, in particular between 10 and 100 μm. |
