Electric conductivities, mechanical properties and friction properties were investigated far graphite-nylon composites impregnated with oil. Specific resistivity of composites containing oil from 2% to 6% were in the range of $10^7 ~10^6 ohm$ cm, which were applicable for anti-static purpose of composites improved by the impregnation of graphite with 2%. Improvement in the impact strength and friction properties of graphite/nylon composites was achieved by the impregnation of oil. The coefficient of friction of the composites containing graphite from 2% to 4% and oil with 2 - 4% showed much loller than that of virgin nylon. Also the abrasive wear of the oil impregnated graphite composites were decreased about 1/3 - 1/10.
