Abstract

Proper selection of floor materials can reduce slip accidents. The present work proposes epoxy floor tiles filled by sand nanoparticles. Friction coefficient and electrostatic charge (ESC) generated from sliding of bare foot, foot wearing socks and rubber footwear on the proposed composites are investigated.
 
It was observed that filling epoxy by sand nanoparticles increased friction coefficient at dry sliding. While at water, detergent and oil wet sliding, friction coefficient showed relatively higher values than that recorded for unfilled epoxy. It seems that sand particles could break the fluid film adhered on both rubber and epoxy surfaces leading to the increase in friction values. Besides, the interaction of the sand particles in rubber surface might contribute extra friction increase. Sliding of bare foot on dry epoxy composites displayed lower friction coefficient than that recorded for rubber shoe. Cotton socks showed the highest friction values followed by polyester and wool. Besides, ESC generated on rubber surface sliding on dry epoxy composites showed the highest values at 1.0 wt. % sand content. Wool socks slid against epoxy showed significant increase in ESC, compared to that observed for cotton and polyester socks. ESC generated on bare foot sliding on dry epoxy composites represented very low values relative to rubber shoe due to the good electrical conductivity of the human body.
