| description | The present application relates to a polyamide composition (P) comprising specific flat glass fibres (B) with elongated shape having a non-circular cross- sectional area. The polyamide composition (P) is advantageously used for the production of molded parts. The invention also relates to use of molded parts obtainable by molding of the polyamide composition (P) to produce mechanical parts. The molded parts are characterized by having improved fatigue resistance properties. In one embodiment, the invention is also concerned with a polyamide composition (P) comprising PA 6.6 as polyamide (A) and flat glass fibres (B) as defined in the claims and specification.
La présente invention concerne une composition de polyamide (P) comprenant des fibres de verre plates particulières (B) de forme allongée ayant une surface de section transversale non circulaire. La composition de polyamide (P) est avantageusement utilisée pour la production de pièces moulées. L'invention concerne également l'utilisation de pièces moulées pouvant être obtenues par moulage de la composition de polyamide (P) pour produire des pièces mécaniques. Les pièces moulées sont caractérisées en ce qu'elles ont des propriétés de résistance à la fatigue améliorées. Dans un mode de réalisation, l'invention concerne également une composition de polyamide (P) comprenant du PA 6,6 en tant que polyamide (A) et des fibres de verre plates (B) telles que définies dans les revendications et la description. |
