Experimental kinetic friction coefficient (μk) determination in the interface polycarbonate blade and flat rubber-belt when interacting with ore, lubricant and pressure
It is well known that even the most advanced Finite Element Analysis (FEA) version is not able to predict friction coefficients among materials. This paper presents an alternative and experimental method based on Design of Experiments (DOE) to determine the friction coefficient between polycarbonate blades against rubber belt. Those experiments correlate ore, lubricant and pressure to determine the friction coefficients in the interface between these materials with polycarbonate and rubber belt. The experiments results are of extreme importance for polycarbonate application on belt conveyor scraper and other applications involving polymeric surfaces under friction.
