In this present research investigation, ethylene propylene diene rubber (EPDM) composites were prepared by incorporating the cellulose short fiber at different phr level and FEF (N550) carbon black on a two roll mill. In the past two decades cellulose short fibers application has attracted a fascinated deal of attention among the rubber composite research community. The effect of cellulose short fiber content on the physico-mechanical properties and rheological properties of EPDM rubber compounds were predominantly studied. It was fairly found that FEF content had greater effect on scorch time when the carbon black phr level was fixed about 50 phr level. The curing characteristics such as cure time, minimum torque and maximum torque with the loading of cellulose short fibers and carbon black used. Incorporating the cellulose short fibres and carbon black in EPDM vulcanizate have tremendously improved the rheological properties and physico-mechanical properties such as tensile strength, elongation at break, hardness, compression set and abrasion resistance which showed the synergistic effect between the fillers. Ethylene Propylene Diene Rubber Composites showed the better abrasion resistance and compression set while the fibres load was fixed as 30 phr.
