Cross sections of silicon and nitrile sheet rubbers were increased to 1.06 and 1.32 times, respectively, by exposure to bio-diesel fuel (BDF) for 112 days. Tensile strength for nitrile sheet rubber was reduced by 41%, and that for silicon sheet rubber was reduced by 12%. These results indicate that aging of nitrile sheet rubber was more rapid than that of silicon sheet rubber in response to exposure to BDF, although the values for reduced tensile strength were around 7 MPa for both of them. No obvious aging on the surface of aluminum alloy was observed in the scanning electron micrographs.
