Properties of epoxy resin composite containing CNTs dispersed by barrier discharge

The epoxy composites containing the dispersed particles of MWCNTs (fiber or coil type) were produced using a two-fluid mixing type epoxy resin. The dispersion of the original CNTs was carried out by the barrier discharge in 2-ethyl-1-hexanol. The tensile stress of the epoxy composites was reinforced by adding a slight amount (0.02 wt% concentration) of the dispersed CNTs. The maximum stress achieved was 53.4 MPa (46.7 MPa in the breaking stress) for the composite containing the fiber type CNTs. These stress value was approximately 1.3 times of the CNT free epoxy resin.
