Reinforced polyamide molding materials, comprise: a polyamide matrix containing (wt.%): (A) aliphatic, partly crystalline polyamides (0-60) with a solution viscosity of more than 1.3 to less than 1.9 (preferably 1.4 to less than 1.9), and (B) at least one amorphous or microcrystalline polyamide (0-60); a filler component containing (wt.%): (C) flat glass fibers (40-80) with elongated shape and the glass fibers have a non-circular cross-sectional area, and (D) particle like or layer like fillers (0-40); and optionally (E) up to 5 wt.% of usual additives and adjuvants. Reinforced polyamide molding materials with high notch impact strength, containing low viscous polyamides and flat glass fibers as a reinforcing medium, comprise: a polyamide matrix containing (wt.%): (A) at least one aliphatic, partly crystalline polyamide (0-60, preferably 20-60) with a solution viscosity (eta r e l), measured in meta-cresol (0.5 wt.%) of more than 1.3 to less than 1.9 (preferably more than 1.35 to less than 1.9, especially mor
