Effect of different volume ratio on resistivity dielectric constant and loss factor of pure epoxy resin: article / Nur Liyana Amni Salauddin

In this paper, epoxy resin based composites with different volume ratio were studied. The relationship between volume rafio change as well as resistivity, relative permittivity and loss factor were investigated. The results show that, the resistivity decrease when hardener (Part A) content are higher than material (Part B) itself after 500V voltage applied on it in 60 seconds. In addition, the permittivity of all sample decrease as the frequency reaches 10k Hz. Yet, loss factor is about to increase when the frequency is increased. Thus, resistivity, permittivity and loss factor of insulation are depending on volume ratio change.
