Wear behaviour of carbon nanotube reinforced epoxy resin composites

Article

Abstract

This paper deals with the effect of a multi-walled carbon nanotube (MWCNT) reinforcement on the wear behaviour of Epoxy (EP) composites. Firstly, various dispersion methods were compared. Secondly, the optimum CNT amount was evaluated. In a third step, dry lubricants were added to the optimised EP/CNT composite. Finally, the influence of the steel counterpart (martensitic bearing steel 100Cr6 and austenitic stainless steel X5CrNi18-10) was studied. The preparation method was found to have a decisive effect on the wear behaviour of the composite. A pre-treatment of the CNTs in concentrated nitric acid proved beneficial. Even more important was the mixing method. A dual asymmetric centrifuge delivered so good wear results that the pre-treatment could be skipped. The optimum CNT content was at about 1 wt%, regardless of the preparation method. The lowest wear rates were found after addition of 10 wt% graphite. MoS2 proved to be less effective and Polytetrafluorethylene (PTFE) even increased the wear. The wear rates against the unalloyed martensitic steel were far higher than against austenitic stainless steel.

Acknowledgments

The authors would like to thank some colleagues from the Fachhochschule Lübeck for their support and helpful discussions: Prof. B. Voß conducted the SEM investigations, Dipl.-Ing. E.-O. Reimann introduced us to the viscosity measurements and provided the according test rig, Ms A.-Ch. Heidenreich and Dipl.-Ing. A. Frederich made the equipment available needed for the pre-treatment in nitric acid. Altropol, Stockelsdorf, Germany supplied the epoxy resin free of charge.
