  • Method and apparatus for ultrasonically testing polymers
    Patent number: 4346599
    Abstract: Apparatus for ultrasonically testing polymer materials includes means for measuring the thickness of the specimen and for measuring the mass density of the specimen in situ. Ultrasonic measurements of the specimen are obtained. Then the specimen holder is rotated past the critical angle and new ultrasonic measurements are obtained. From these ultrasonic measurements the storage and loss moduli and attenuation coefficients for the polymer specimen are obtained.
