Friction clutches are still the most widely used type of coupling especially in passenger vehicles. Structural construction of friction clutches is not changed significantly, but their performance is what is constantly being improved. Among other factors that determine the life of the friction clutch i.e. of the friction disk is the quality and friction characteristics of linings. This paper presents the results of experimental research of the impact of the material composition of the linings on the tribological parameters. Specifically are shown the improvements that can be achieved with the use of basalt thread in the material composition of the friction linings.
