THERMOPLASTIC COMPOSITE MATERIALS

A collection of particles made of a thermoplastic composition comprising at least one semi-aromatic polyamide are provided which have a median particle size on a volume basis, D(v, 0.5), from 0.1 to 50.0 μm and an asymmetric particle size distribution. The collection of particles are suitable for th...

More Information
Summary:A collection of particles made of a thermoplastic composition comprising at least one semi-aromatic polyamide are provided which have a median particle size on a volume basis, D(v, 0.5), from 0.1 to 50.0 μm and an asymmetric particle size distribution. The collection of particles are suitable for the preparation of composite materials comprising continuous fibers by a slurry impregnation process. L'invention concerne une collection de particules constituées d'une composition thermoplastique comprenant au moins un polyamide semi-aromatique qui ont une taille de particule médiane sur une base volumique, D(v, 0,5), de 0,1 à 50,0 µm et une distribution de taille de particule asymétrique. La collection de particules est appropriée pour la préparation de matériaux composites comprenant des fibres continues selon un procédé d'imprégnation de suspension.
