In this paper, the temperature dependence of the strength of adhesively bonded shear lap joint reinforced with multi-walled carbon nanotubes (MWCNTs) was studied. The results showed that increasing the testing temperature diminished the improving effect of MWCNTs to the extent that beyond a critical temperature, adding nanofillers even degraded the shear strength of adhesive joints. Furthermore, using a proposed mathematical model, the optimum MWCNT weight percentages for the MWCNT-reinforced adhesives tested under different temperatures were obtained. Moreover, the scanning electron microscopy technique was used to determine the running micro-mechanisms.
