Abstract

The purpose of the current work is to show the effect of multi-walled carbon nanotubes(MWCNTs) of 0.1, 0.2, 0.3, 0.4 and 0.5 wt. % contents reinforcing polymethyl methacrylate (PMMA) on the frictional behavior of this composite when sliding against emery paper. The hardness of the intended composites is measured by Shore D Durometer on the surface and side of the test specimen. Friction coefficient of MWCNTs/PMMA composites is measured by a reciprocating sliding apparatus at room temperature.
Based on the experiments, results display that the hardness of hot cured tested composites increased gradually by increasing MWCNTs content unlike the cold cured composites. In addition to that, it is shown that friction coefficient of hot and cold cured composites decreased by adding 0.1, 0.2, 0.3, 0.4, and 0.5 wt. % of MWCNTs. Also, friction coefficient of the tested composites was found to be significantly affected by the normal load. Based on these results, it may be stated that hardness of the tested composites is dependent on curing type and MWCNTs content. Besides, friction coefficient of the tested composites is dependent on MWCNTs content and normal load. It can be concluded that hot cured composites are better than cold cured composites to be used in different engineering application.
