Abstract
In this work, the influence of amount (30 and 40 wt.%) of short glass fibers (SGF) in two composites containing synthetic graphite (10 wt.%) and Polyaryl ether ketone (PAEK) (60 wt.% and 50 wt.%) on thermal, mechanical and tribological performance was studied. The theme was to investigate wear-mechanical property correlation. Although the higher amount of SGF led to higher mechanical properties, tribological properties were not in tune to this. Overall, friction coefficient (µ) and specific wear rate (K0) for the composites were in the range 0.04–0.08 and 3–8 × 10−16 m3/Nm respectively and decreased with increase in applied PV values till failure was observed. PVlimit was indicated at 112 and 100 MPa m/s for 30 wt.% and 40 wt.% SGF filled composites respectively. The mechanical properties of the composite with 40 wt.% GF (CGF40) proved superior to a composite with 30 wt.% GF (CGF30).
