Experimental investigation of tread compounds frictional properties

The friction properties of vulcanized rubber were investigated. The friction force between planar sample and chosen surface at various values of sliding velocity and normal pressure was measured. The experimental equipment based on standard tensile machine 1NSTRON 4302 was used. The samples of tread compQunds and some materials (asphalt, concrete, glass, steel) were tested. The experimental dependencies of the friction coefficient to the sliding velocity show good agreement with published experimental and theoretical results.
