Abstract

The influence of PTFE and Graphite fillers on erosive wear behavior of Glass Fiber – Vinyl Ester composites are analyzed. The mechanical properties such as tensile strength of the composites have also been reported. The erosive wear behavior of the composites was tested using air jet erosive wear testing machine at varying impingement angle (300, 600, 750, 900), Experiment were conducted using aluminum oxide(Al2O3) of 50 micron as erodent particles at constant air jet speed 75 m/sec, discharge rate of erodent was 10 gm/min, pressure 0.8 bar at atmospheric condition. A significant reduction in wear loss and specific wear rates were noticed after incorporation of PTFE and graphite filler into the glass-vinyl ester composite. This result indicates that the significant influence of PTFE and graphite filler allowing less wear of matrix during erosion which in turn facilitates lower fiber damage, due to the presence of PTFE/graphite particles on the counter surface, which act as a transfer layer and effective barriers to prevent large-scale fragmentation. The result also showed that the 10%PTFE filler by weight ratio to polymer composition composite show’s less wear than S-glass vinyl ester reinforced composite and 10% graphite filler reinforced S-glass vinyl ester.
