Abstract

L'invention concerne un non-tissé de fibre composite frisée et un stratifié correspondant, ainsi qu'un article. Le non-tissé de fibre composite frisée selon l'invention est un non-tissé de fibre composite frisée comprenant un premier polymère à base de propylène et un second polymère à base de propylène. Dans le premier polymère à base de propylène et le second polymère à base de propylène, le point de fusion du second polymère à base de propylène, mesuré à l'aide d'un calorimètre différentiel à balayage (DSC), est supérieur d'au moins 30 °C au point de fusion du premier polymère à base de propylène, un rapport (second polymère à base de propylène/premier polymère à base de propylène) de vitesses de fusion (MFR : température de mesure de 230 °C, charge de 2,16 kg) entre le premier polymère à base de propylène et le second polymère à base de propylène, mesuré conformément à la norme ASTM D1238, est supérieur ou égal à 1,7, un rapport (second polymère à base de propylène/premier polymère à base de propylène) de distributions de poids moléculaire (DPM) entre le premier polymère à base de propylène et le second polymère à base de propylène, mesuré par chromatographie par perméation de gel (CPG), est supérieur ou égal à 1,5 et un rapport de constituants représenté par le premier polymère à base de propylène/le second polymère à base de propylène (rapport pondéral) est de 50/50 à 10/90.
