Abstract

In this paper we examine the effect of pre-strain (or biased strain) and temperature on interfacial slip in singlewalled carbon nanotube polycarbonate composites. The nanotube composite is tested under uni-axial sinusoidal loading to characterize the baseline response (storage, loss modulus) of the material. Next a biased strain (0 to 0.85%) is applied and then the sinusoidal load is superposed on to the pre-strain. The results indicate a significant damping enhancement which suggests that pre-strain facilitates the activation of nanotube polymer interfacial slip. Next we tested the nano-composite under sinusoidal loading with zero pre-strain, while changing the temperature in the 25-90°C range. The results indicate that temperature also facilitates the activation of interfacial slip leading to a significant increase in energy dissipation.
