Efficiency of polymer materials in highly loaded systems in the aviation industry

open access: yesAviation, 2023
The static coefficient of friction was calculated on an inclined plane tribological stand. Different specimens and masses loading the system were used during the experiment. Surface-to-surface contact was tested in a pin-on-plate setup.

Experimental Study on the Transition between Static and Kinetic Frictions of Steel/Shale Pairs

open access: yesShock and Vibration, 2021
The transition between static and kinetic frictions of steel/shale pairs has been studied. It was found that the coefficient of friction decreased exponentially from static to dynamic friction coefficient with increasing sliding displacement.
