Experimental investigation on multidimensional carbon nanofiller reinforcement in HDPE: An evaluation of mechanical performance

The current work reports on the evaluation of mechanical properties of HDPE reinforced with multidimensional carbon based nanofillers: Nanodiamonds (ND)-0D, Multiwalled Carbon Nanotubes (CNT)-1D and Graphite nano Platelets (GNP)-2D. A twin screw injection molding machine was used to fabricate samples and designated according weight percentage of nanofiller in pure HDPE as 0.1 ND, 0.1 CNT,and 0.1 GNP respectively. The optimum mechanical properties was exhibited by 0.1 ND, with a noted increase of 33.6, 23, 42, 34% in hardness, Young‘s modulus, fracture stress and yield stress as compared with pure HDPE. Halpin Tsai equation was used to predict Young‘s modulus of composite and results confirmed a close agreement between predicted and experimental observations.
