Carbon Nanotube-Based Reinforced Polymers for Medical Applications: Improving Impact Strength of Polymer-Polymer Composites

Figure 3

Results of mechanical tensile tests applied to the proposed HDPE-UHMWPE-MWCNT-based samples. The measurements correspond to Young’s modulus (a), yield point (b), ultimate stress (c), elongation at ultimate (d), fracture stress (e), and elongation at break (f). The -axis represents the mixing ratios for HDPE-UHMWPE-MWCNTs in (%), while the -axis corresponds to the physical characteristics, which are measured in units of MPa or percentage, as appropriate. The bars (blue) and error bars (black) correspond to the mean value ( and standard deviation (SD)) from five measurements, respectively.
