| Abstract | ||
| In this research we have prepared nanocomposite material based on polymeric material which it Poly methyl meth acrylate (PMMA) and doped by Copper Nanoparticles (Cu) with different weight percentages (5wt%,10wt%). The Ultrasonic Waves Velocity had been measured by Ultrasonic Waves system with frequency(25KHz). Absorption Coefficient, Relaxation Amplitude, Compressibility, Bulk Modulus and Specific Acoustic Impedance have been calculated at room temperature. . The results showed that all properties increased Linearly with increasing the concentration of Copper Nanoparticles (Cu) except the Compressibility that decreased with increasing the concentration | ||
