| Summary: | Elastomeric materials are widely used in daily applications, such as conveyor belts and
wiper. Generally, elastomeric materials show poor tribological behavior. Adding fibers
to an elastomer is a way to solve this problem. The orientation of the fibers influences the
mechanical and tribological behavior of the elastomers. In the present study, the effect of
short-cut aramid fiber orientation on the tribological behavior for a Styrene-Butadiene
Rubber (SBR) was examined. Three types of compounds which have different fiber
orientations were prepared, resulting in normal, transverse and longitudinal orientation to
the sliding direction. A contact model of the viscoelastic-anisotropic behaving elastomer
was used to calculate the contact area. The friction and wear of the compounds were
evaluated using a pin-on-disc tribometer. The results show that the frictional shear
stresses of all compounds are nearly the same due to the presence of fibers on the wear
track. The normal orientation of fibers shows the most effective way to increase the wear
resistance compared to the longitudinal and transverse orientation of the fibers. |
