Effect of swelling process on the thermoelastic temperature change of ethylene propylene diene rubber filled with carbon black

Abstract

The effects of both dynamic cyclic extension and swelling on the thermoelastic behavior of ethylene propylene diene rubber loaded with different concentrations of carbon black have been studied. As the strain amplitude increases, the concentration of the ruptured bonds increases, leading to more enhanced friction between particles and consequently to the observed rise in temperature. Temperature change was found to be highly dependent on the swelling and also on carbon black concentration.
