Abstract
The ultrasonic properties of self-adhered SBR (single-, double- and triple-layered) have been investigated as a function of both carbon black (HAF) content in one layer and temperature. The propagation velocity and the absorption per wavelength of longitudinal ultrasonic waves of frequency 2 MHz have been measured in the temperature range from 27°C to 120°C, by pulse echo immersion technique. The variation of the longitudinal ultrasonic modulus with temperature has been derived from these measurements. The percolation concentration of HAF black was confirmed to lie at about 35 phr.
