Abstract

The dependency of friction coefficient on electrostatic charge (ESC) generated from sliding of polyethylene (PA) on polytetrafluoroethylene (PTFE) is investigated. The effect of reinforcing PTFE by carbon fibres (CF), copper and iron wires is tested. Besides, PTFE has been filled by layers of carbon black, copper and iron particles and tested. Tests have been carried out at dry sliding.
 
It was found that ESC generated on PA and PTFE reinforced by CF and friction coefficient increase as CF content increases. This observation strengthens the dependency of friction coefficient on ESC. Therefore, specific information about the value of ESC can be useful in controlling friction coefficient. This behavior can be explained on the bases that increasing ESC can increase the adhesion between the two contact surface and consequently friction coefficient increases. Besides, ESC can be controlled by applying magnetic or electric field. This behavior can be used in controlling friction coefficient of polymeric material when they are contacting each other. Finally, ESC generated on PA surface for composites containing iron particles showed the highest values followed by copper particles and carbon black. Generally, filling materials in form of particles generated higher ESC than that in form of wires. Friction coefficient displayed the same order observed for ESC, where iron showed higher values than copper and carbon black. That observation may recommend the application of layers of iron or copper particles to control ESC and friction coefficient.
