An experimental study of the scratch properties of poly(methyl methacrylate) as a function of the concentration of added slip agent

초록

A scratch test was performed on poly(methyl methacrylate) (PMMA) material that had been optimised for electronic products. In this study, the scratch properties of PMMA containing various concentrations of slip agent were investigated by performing scratch tests under two different load conditions, i.e., a static normal load and a variable normal load. The effects of the concentration of slip agent on the scratch properties of PMMA were characterised by some key tribological parameters, based on a new standard test methodology. Additionally, the damaged surfaces of the specimens were investigated to understand the variations in scratch mechanisms. (C) 2011 Elsevier Ltd. All rights reserved.
