Rubber On Ceramic Coefficent

Abstract the present work describes the frictional behaviour of ceramic tiles as flooring materials when soft and hard rubbers slide against them.

Rubber on ceramic coefficent. The rubber test specimens displayed the highest value of friction coefficient. Example friction force. The values of friction coefficient displayed by sliding of rubber against different types of flooring materials would be compared to that obtained from ceramic tiles. C o m w w w.

Before 2014 the standard for rating the slip resistance was based on the static coefficient of friction scof determined by the astm international test method c1028. The static and kinetic friction coefficient values reference table shown in this article will be helpful for finding the cof values of commonly used materials. The friction force can be calculated as. For oil lubricated ceramic friction coefficient decreased with increasing height of the grooves introduced in the rub ber specimens.

Tests have evolved over the years and the current test dcof acutest developed by the tile council of north america is intended to replicate real world conditions more than did the older tests. Introduction slip resistance of flooring materials is one of the major environmental factors affecting walking and materials handling behavior. Note that static coefficients are somewhat higher than the kinetic or sliding coefficients. March 1st 2018 update.
