Abstract

The present study is part of wide research project conducted by authors, whose overarching purpose is to develop design recommendations for epoxy floor materials regarding friction requirements and slip resistance based on friction measurements and avoid danger of electro-static charge generating during walking.
 
The epoxy test specimens in a form of a tile of 150 × 150 mm2 prepared by mixing copper chip with epoxy resin then poured on wooden block. The tested materials were epoxy filled by different contents of copper chip with 5 micron particle size. The copper chip was added to epoxy with different content 1, 2, 3, 4 and 5 wt. %. The Friction test was carried out at different values of normal load, for covering the light and heavy loads for persons. The sliding behavior measure by use the rubber shoes with 63, 65 and 67 shore A hardness. Static friction coefficient was measured at the start of sliding.
 
Test results showed that, the epoxy filled by copper chip show remarkable increases in friction coefficient and reduces electrostatic charge accumulated on contact surface. At water sliding conditions, the water helps for release of the electrostatic charge out of contact surfaces. Thus, the value of electrostatic charge reduces in water wet condition. The friction coefficient increase with adding copper chip to epoxy resin in all types of rubber shoes. Adding copper chip to epoxy resin as floor materials show significant reduction in electrostatic charge generated from sliding of rubber shoes against epoxy floor materials.
