Experimental study on mechanical properties of PE / CNT composites

Armin Najipour, A. M. Fattahi
High density polyethylene/carbon nanotube composites have been produced for investiga-
tions. Four CNT volume fractions and two injection pressures were considered. According to
the Taguchi approach, eight experiments were designed. The effect of the carbon nanotubes
weight fraction and injection pressure on hardness and impact strength of nanocomposite
samples were investigated. The results showed that the effect of the carbon nanotube weight
fraction on hardness and impact strength of nanocomposite samples was much higher than
the effect of injection pressure. By adding 1%wt (weight) carbon nanotube into the polymer,
the impact strength and hardness of the samples improved by 74% and 47%, respectively.
