US Patent 9221974 Reinforced polyamide moulding materials

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.
