Conducting polymer composite (CPC) has produced used epoxy resin (EP), carbon black (CB) and graphite (G) as main composition. Various weight percentage (wt.%) of CB, G and EP has been selected. The fillers (CB and G) were mixed together with the matrix (EP) used high speed mixer with no heat treatment. The mixture was poured into the steel mold and formed used hot pressed. After that, all sample’s electrical conductivity and flexural strength had been measured and the properties of EP/CB/G composite was analyzed. The result found that the best plate produced was the 20/25/55 of EP/CB/G weight ratio (wt.%). It has 102 S/cm in-plane electrical conductivity and 12 MPa flexural strength.
