The gasket rubber material used in the fuel cell is compressed for a period of more than 80,000 hours when the durability is guaranteed for 10 years. Thus it is necessary to develop a rubber material that maintains high elasticity for a long period of time to maintain sealing during the use time and is highly resistant to compression strain. Recently, EPDM emerged as an alternative material to Fluorine rubber (FKM) rubber which was mainly used as a fuel cell gasket material due to its good injection moldability and the low production cost compared to FKM. But it is necessary to supplement heat resistance and mechanical properties in order to using EPDM rubber. In this study, we focused on reinforcement property of nanoclay on EPDM composites. To investigate the nanoscale structure of EPDM nanocomposites, a transmission electron microscope (TEM) was used. Also, to compare nanoclay and other fillers, mechanical properties of samples were characterized by tensile test and compression set. |
