Dynamical Properties of Polymer Matrix Composites by Ultrasonic Waves

Zusatztext

Dynamical properties (compressional velocity (Vp), shear velocity (Vs) Poisson ratio (), shear modulus (G), and modulus of elasticity (E), bulk modulus (B), Acoustic impedance (Z), and attenuation coefficient () were calculated for EP/ laminate, and chopped rock wool composites without and with immersion in water for 15,30, and 45 days at room temperature. Results of Vp, Vs, G, E, Z, and of EP/laminate, chopped rock wool composite without immersion in water had obtained.
