In this research prepared composites from epoxy – carbon nano tube using hand lay method with different volume ratios of carbon nano tube (CNT) ( 0,1,2,3,4,5)% To weight carbon nano tube different ratio (1,2,3,4,5%) by using sensitive electrical balance (0.001gm) added CNT with epoxy with stirrer at 60c one hour after that added hardener and stirrer five minute. Make electrical tests to find the electrical conductivity increased with increased ratio of CNT and activation energy decreased with increasing ratio of CNT . dielectric constant and dielectric loss decrease with increasing frequency . Dielectric constant measure the electric properties of a material as a function of frequency the frequency dependence of dielectric constant 'e at two temperature 20 and 60 °c .
