The quasi-longitudinal elastic wave ultrasound (US) velocity measuring V║ = 3333 ± 10 m/sec, dynamical elastic modulus E = ρV║2 = 13,719 GPa, the quasi-transversal US velocity V┴ = 1215 ± 10 m/sec, shear modulus G = ρV┴2 = 1,823 GPa of nanocomposite polyamide-6 (PA-6) (NH(CH2)5CO)n + 1.7% methylene dye blue squaring (DBSQ) were determined from the oscillogram in Fig. 1 [1].
