Abstract
In this work the internal friction (Q-1) measurement of different types of elastomer using pulse excitation technique which is a non-conducting high efficient method is discussed. The Natural rubber (NR), Styrene Butadiene Rubber (SBR) and Nitrile Rubber (NBR) elastomers were chosen for this work. They were loaded with different ratios of N220 and N774 Nano-sized carbon black fillers. For the measurements, the samples of NR, SBR and NBR, prepared to be in a string shape of dimensions of 200mm long and of homogenous circular cross section of 3mm diameter were used.
