Abstract

The knowledge of elastic properties of the various types of rubber is significant for many commercial and academic applications. A sample set consisting of generic elastomeric compounds was studied using non-destructive non-contact ultrasonic techniques. The longitudinal sound wave velocities in the sample and wave amplitude attenuation in the sample were measured using the Second Wave Inc. Non-Contact Analyzer 1000 (NCA1000). The Contact method was then used to corroborate the results obtained. A rule-of-mixture model was used to compare the velocity values obtained by the non-contact technique. The preliminary results suggest that the differences in attenuation are driven by polymer type and also to a lesser extent by the loading level of carbon black fillers.
