Abstract

A nanoengineered hybrid composite system has been developed, with integrated damage sensing capabilities at extremely low carbon nanotube CNT contents. The employed simple spray coating technique offers good spatial control and the possibility of localized CNT deposition, especially near the fibre-matrix interface, solving traditional problems associated with the incorporation of nanofillers in fibre-reinforced composite laminates such as increased resin viscosity and filtering effects. Moreover, the employed spraying technology has good potential for industrial scale-up. In situ damage sensing based on standard composite tests has been demonstrated for the first time on hybrid glass fibre-CNT composites using extremely low CNT loadings below 0.1 wt.% and shows great potential for localized structural health monitoring by controlled CNT deposition into damage prone zones.
