Beschreibung
Zusammenfassung:	Disclosed is a injection molded composite wheel, including a polyamide composition including (A) about 20 to about 70 weight percent of at least one polyamide resin, (B) about 30 to about 65 weight percent of one or more fiber reinforcing agents wherein the fiber has an average length of 0.1 to 0.9 mm; and (C) 0 to about 20 weight percent of one or more polymer impact modifiers; wherein 4 mm test bars prepared from the polyamide composition have an average tensile modulus greater than or equal to about 9 GPa, and an elongation at break of at least 4 %. La présente invention concerne une roue composite moulée par injection, comprenant une composition de polyamide comprenant (A) environ 20 à environ 70 pour cent en poids d'au moins une résine de polyamide, (B) environ 30 à environ 65 pour cent en poids d'un ou plusieurs agents renforcés en fibres, la fibre ayant une longueur moyenne de 0,1 à 0,9 mm ; et (C) 0 à environ 20 pour cent en poids d'un ou plusieurs modificateurs d'impact de polymère ; des barres d'essai de 4 mm préparées à partir de la composition de polyamide ayant une moyenne de module de traction supérieure ou égale à environ 9 GPa et un allongement à la rupture d'au moins 4 %.
