Tribological performance of polyester composites filled by vegetable oils

In the present work, friction coefficients and wear rates of polyester composites reinforced by graphite fiber with different diameters and impregnated by vegetable oils (Corn, Olives, and Sunflower oil) were measured to develop new engineering materials with low friction coefficients and high wear resistance which can be used in industrial applications as bearing materials. It was found thatcomposites of 10 vol.% corn oil and 10 vol.% graphite fibers show relatively low friction coefficientsand low wear rates. Corn and sunflower oil display good tribological behavior of the polyester composites.
