Abstract
Described herein is a polyamide composition (P) including 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. Also described herein is a method of using 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. Also described herein is a polyamide composition (P) including PA 6.6 as polyamide (A) and flat glass fibres (B).
