Abstract :
A set of multi-wall carbon nanotubes (MWCNTs)/graphite/epoxy (EP) composites were used to form piezoresistive strain sensors for structural health monitoring applications. The static resistance of epoxy composite with different concentrations of MWCNTs and graphite was tailored. And a steel equivalent moment beam was used for modeling and testing the response of the sensors. The effect of the concentrations of MWCNTs, also the synergistic effect of MWCNTs and graphite on the sensitivity of the sensor was studied. The results show that the carbon nanotubes/graphite/epoxy resin sensor has a fairly linear symmetric strain response under static strain.
