Abstract

The elastic and inelastic behavior of carbon nanotube reinforced polystyrene is investigated at room temperature. The composites were manufactured using a solution evaporation technique to produce specimens that were tested on a conventional universal testing system. The addition of 3 wt% nanotubes caused an increase in the Young's modulus of 12.3%. In addition, cyclic stress experiments were conducted to determine both the instantaneous strain recovery and the energy dissipated under tensile loading. The specimens were loaded to 2 MPa at constant loading and unloading rates of 1 mm/min and 5 mm/min. More energy was dissipated for the nanocomposites and higher strain rates. Conversely, more strain recovery took place at slower strain rates and for the pure polystyrene samples. Stress relaxation experiments showed that there is at only about a 1% difference in time dependent modulus between pure polystyrene and nanotube reinforced polystyrene.
