Abstract

The relatively low static friction coefficient displayed by sliding of soles on floor tiles is considered as the major reason in walking accidents indoors. The present work studies the effect of reinforcing epoxy by natural fibers such as wood, rice straw and palm fibers on friction coefficient to guarantee the availability be used as floor material and enhance the tribological and mechanical properties.
 
The experimental observations revealed that wood fibers reinforced composites displayed friction coefficient of values higher than that recommended in the universal building codes (0.5). It was found that friction coefficient slightly decreased with as the fiber content increased. While, significant increase in friction coefficient was caused as the applied load increased due to the increase of the contact area. Rice straw fibers experienced lower values of friction coefficient compared to wood fibers. Further decrease in friction coefficient was observed for composites reinforced by palm fibers.
