Composites have replaced metals in the bearing industry for the exclusive performances from its properties were it can accommodate resins, fabrics and additives. Roll-slip is common behaviors in application were non-conformal contact exhibits like bearings, rollers and cams. Two elements control the tribological behavior of the material which is the rolling and the sliding element. Composite-steel contacts were tested using a twin-disc setup with open tribo-system to study the influence of load on the frictional behavior of the polymer composites. The contacts were tested with four different loads under 20% slip ratio for a regular interval of time. The curves from the friction force with respect to different loads follows a tendency of linear increase in friction force were the rolling resistance is the dominating mechanism. For the given condition the macro level investigations shows the absence of transfer layer on the steel counterparts. The tendency of the friction curve and the micrograph explicitly deliberates the involvement of abrasion and adhesion in the harder polymer from metal counterpart. The temperature variable is isolated in case of the above research. The examination of the contact surface reveals the formation of craters on the junction of polymer and textile.
