Structural and mechanical properties of epoxy resin/jeffamine-D400 reinforced by multiwall carbon nanotubes

Polymer nanocomposites reinforced with carbon nanotubes have been attracted by many researchers. The properties of nanocomposites depend greatly on the chemistry of polymer matrices, nature of nanofillers and the way in which they are prepared. Properties of epoxy resin have a significant influence on the mechanical properties of the nanocomposites. In this paper the effect of matrix hardness on the mechanical properties of the carbon nanotubes reinforced epoxy composite has been studied and an experimental investigation of the effect of nanotubes on the mechanical properties of the composites was reported. In this study, epon-828 and jeffamine-D400 were used. Multiwall carbon nanotubes/epoxy resin composites have been fabricated and the mechanical properties of the composite with different weight percentages of nanotubes have been obtained. A sonication technique was used to disperse nanotubes in epoxy matrix. Particular attention is paid on the structure property relationship of such novel high performance polymer nanocomposites when the matrix is reinforced with E-glass. The results have shown that ultimate stress and strain for different percentage of nanotubes is increased
