Preparation and Tribological Behavior of Carbon Fiber Reinforced Pantograph Slide Plate
Abstract:
The carbon fiber (CF) reinforced pantograph sliding plates were fabricated by hot pressing with modified phenolic resin as bonder, and the continuous carbon fiber, copper and graphite respectively were reinforcing phase, electric conductive phase and lubricating phase, respectively. The impact toughness, electric resistance and wear resistance of the slide plate were tested. The structural characteristics of the pantograph sliding plates were investigated by scanning electron microscopy (SEM). The results show that the addition of CF mass fraction can increase impact strength and density; while resistivity has a lower trend; the volume abrasion loss and friction coefficient are decreased then increased dramatically. The fiber and resin interface adhesion is good for specimen impact cross section smooth. In addition, adhesive wear and abrasive wear are the main wear form of pantograph slide plates.
