Use of epoxy/multiwalled carbon nanotubes as adhesives to join graphite fibre reinforced polymer composites

In this study, different weight fractions of multiwalled carbon nanotubes were dispersed in epoxy to produce toughened adhesives. The reinforced adhesives were used to bond the graphite fibre/epoxy composite adherends. Single lap joint samples were prepared and the average shear strengths were experimentally measured. Significant enhancement of the bonding performance was observed as the weight fraction of carbon nanotubes was increased.
