Abstract: The present invention relates to a composite material comprising a warp-knitted textile panel having wales corresponding to the warp direction and courses corresponding to the weft direction, and first and second opposite faces, said first face being covered with a layer of at least one polymer material. Advantageously, each of said wales includes first stitches formed on every other course with a first yarn, and second stitches formed on every other course with a second yarn, the first and second stitches being alternated on every other course and being in opposite directions. In addition, in the weft direction, the first yarn and the second yarn each form stitches on every other course in alternation.
