Özet

Wear and frictional behaviours of polypropylene (PP) and 10%, 15%, 17.5% glass fiber reinforced polypropylene (GFRPP) materials were studied against SAE1040 steel counterface block-on-ring apparatus at different sliding speeds and constant normal force load. Increasing the sliding distance increases the weight loss at all speed tested. 200 rpm wear rates are increased irrespective of reinforcement rates and for the maximum rotational speed (500 rpm) wear rates are de creased irrespective of reinfocement rates. Thermo-mechanical properties of glass fiber reinforced PP were examined using DSC and Shore D hardness devices. Microstructures of worn surface of the tested materials were inspected by scanning electronic microscope (SEM) and wear mechanism of the tested materials were studied. Worn surfaces of the tested materials showed that the adhesive wear played an important role for pure polypropylene and with the addition of glass fiber, the wear mechanism was a combination of adhesive and abrasive wear.
