  • Patent number: 8846800
    Abstract: The present invention relates to reinforced polyamide molding materials which can be prepared from a polyamide blend and, for example, by compounding with cut fibers or continuous filaments on twin-screw extruders and have mechanical properties which are usually not compatible with one another, namely a combination of exceptionally high rigidity and strength and at the same time good toughness. Furthermore, a high heat distortion temperature (HDT) is achieved according to the invention. The thermoplastic polyamide molding materials according to the invention are suitable for the production of moldings or other semifinished products or finished articles, which can be produced, for example, by extrusion, injection molding, direct methods or direct compounding, in which the compounded polyamide molding material is processed directly by injection molding, or other deformation techniques.
