Fluororubber(FKM) Nanocomposites modified by attapulgite(ATP) and graphite(GP) were prepared by comixing and heat molding.On the base of the curing histories,tensile strength and elongation at break,frictional properties of FKM composites were analyzed.The results indicate that with the addition of ATP in the composites,its apparent cross linking density and tensile strength were increased.When the phr of GP and ATP in FKM composite was 3 and 1,FKM compostes had more lower the coefficient of friction (COF) and wear rate.During the process of sliding friction,when the ratio of ATP and GP was fit,ATP and GP of exfoliating from frictional surface with FKM produced transfer film of reducing friction and wear resistance,and FKM composite showed better frictional properties.
