RESEARCH ON FRICTION AND WEAR BEHAVIOR OF MULTI-WALLED CARBON NANOTUBE/EPOXY COMPOSITES

Abstract

Abstract: Epoxy resin curing presents 3D cross-linking network structure characteristics,resulting in epoxy resin displaying a lower wear resistance,which limits its extensive applications. To overcome this disadvantage,in this paper,the effects of adding carbon nanotubes into epoxy and electroless plating on friction and wear behavior of epoxy-based composites were studied. The results showed that the friction coefficient and wear rate of the epoxy composites with 0.5wt% amino-MWCNTs are 0.314 and 0.93×10^-4 g·min^-1,respectively. Compared with the neat epoxy,its wear rate decreased by 41.3%. Thus,the friction coefficient and wear rate were effectively decreased by adding carbon nanotubes into epoxy and the wear resistance was improved. Meanwhile,Ni-P-CNTs composite coating was brought into epoxy composites surface by electroless plating. It was found that Ni-P-CNTs coating further decreased the wear rate of composites. Thus,combining the addition of carbon nanotubes with electroless plating technology is an effective method to improve the wear resistance of epoxy-based composites.

Key words: epoxy, carbon nanotube, electroless plating, friction and wear behavior
