Abstract
Directly measured data for high frequency dynamic properties of natural rubber at room temperature are presented. The two experimental techniques employed are first forced non-resonance using a high frequency servohydraulic machine which allowed measurement up to 600 Hz and second forced longitudinal vibration of a viscoelastic bar a method extending the frequency range up to about 1500 Hz. Close agreement is shown to exist between the direct measurement and other data measured over a range of temperatures at low frequencies and transformed to high frequencies by applying the time-temperature equivalence principle. Some low frequency data in the literature however do not when transformed show such good agreement with the present direct measurements. These show that the dynamic modulus of unfilled NR is fairly constant at room temperature up to 1500 Hz whereas its loss factor increases by a factor of 4 from 100 Hz to 1000 Hz.
