Abstract: Epoxy/CNT nanocomposites were synthesized in various ways to examine the effects of dispersion methods on its tribological properties. The carbon nanotubes (CNTs) were pre-treated in three different ways: no pre-treatment, activation in HNO3, and activation in HNO3 plus application of a coupling agent. The dispersion and mixing methods used were: dual asymmetric centrifuge, sonication, hand mixing. The CNTs were mixed either into the hardener or the resin.    The curing behaviour was studied via DSC, and the thermomecanical properties were determined using a DMA. The tribological properties were investigated in a ball-on-prism test rig under unidirectional continuous sliding against austenitic stainless steel.
