Abstract
The self-sealing rubber material for a fuel cell which has self-sealing ability, in case of fuel leakage, was studied. Cure characteristics, density, swelling, and surface morphology of foamed natural rubber were investigated with carbon black and with processing oil within the range of $10{\sim}30phr$. The rheological properties indicated that the value of $ts_2$ and the value of $Tc_{90}$ were increased with increasing a content of processing oil, while carbon black did not show a similar trend. A difference in density by foaming was decreased to one fifth scale compared to the initial value. According to the swelling test of foamed natural rubber in fuel C, isooctane and toluene, all the self-sealing action was finished in two minutes. From the SEM image for the surface of rubber compounding, a foaming by sodium bicarbonate was found to be unequal and consecutive foaming cell.
