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.

Reinforced polyamide moulding materials

The invention relates to filled polyamide molding compounds which, in addition to a selected polymer mixture comprising two different polyamides, contain long glass fibers with a non-circular cross-sectional area. Furthermore, the invention relates to the use of such molding compounds for the production of molded articles and the molded articles themselves.
