Abstract

L'invention concerne un matériau composite de type bande souple (2) comprenant un substrat de type bande (3) contenant au moins en partie un premier polymère thermoplastique, et un matériau non tissé de type bande (4) contenant au moins en partie un second polymère thermoplastique. Le substrat de type bande (3) et le matériau non tissé de type bande (4) sont raccordés l'un à l'autre au niveau de leurs surfaces opposées (3a, 4a), qui forment une surface de raccordement, par l'intermédiaire d'une pluralité de points de raccordement répartis distincts, les points de raccordement étant constitués de particules (7) contenant un troisième polymère thermoplastique, les particules (7) adhérant sensiblement uniquement aux surfaces opposées (3a, 4a) du substrat (3) et du matériau non tissé (4). Les points de raccordement répartis distincts sont disposés à distance les uns des autres, des espaces vides étant prévus entre eux. Les particules (7) viennent en prise par complémentarité de forme dans les espaces creux du matériau non tissé (4).
