Polyetheretherketone (PEEK) stands out for tribological applications due
to its high mechanical properties, excellent chemical and thermal resistance,
and self-lubricating nature. It is often reinforced with carbon fibers (CF) to
enhance its friction and wear performance. Besides the matrix and reinforcement
elements, lubrication conditions also play a significant role in the
tribological performance of composite materials. This study focuses on the
effects of lubrication conditions on the friction and wear performance of
carbon fiber reinforced polyetheretherketone composites (CF/PEEK) by subjecting
them to wear in different environments. The tests were conducted using a
block-on-ring test apparatus under constant normal force (100 N), sliding
velocity (1.5 m/s), and sliding distance (200 m) parameters in dry, water, and
oil lubrication environments. At the end of the tests, data on the coefficient
of friction, volume loss, and wear rate were reported. It was found that under
water and oil lubrication conditions, compared to dry conditions, lower
coefficient of friction, volume loss, and wear rate occurred. A stereo
microscope was used to obtain two-dimensional images of the worn surfaces. By
measuring the wear track dimensions, volume losses and wear rates were
determined. Understanding the friction and wear performance of polymer matrix
composites in different environments will enable the development of
wear-resistant materials for application areas.
