Abstract: A rubber composite material was prepared by adding various amounts of carbon nanofibers functionalized with an amine group through surface modification to EPDM (Ethylene Propylene Diene Monomer) rubber. Changes of the cure and physical characteristics of composite materials were investigated according to contents of carbon nanofibers. Basic physical properties, heat resistance, anti-freezing resistance, and compression set at high/low temperature of rubber composite materials were measured. After adding 1~7 phr of carbon nanofibers functionalized with an amine group through surface modification to EPDM rubber, various physical properties were measured. As a result, basic physical property, heat resistance, and anti-freezing resistance of rubber composite materials added with 5~7 phr of carbon nanofibers showed improved physical property the most.
