Investigation of mechanical properties of high-density polyethylene/carbon nanofibers nanocomposites produced by extrusion method

In this work, the mechanical properties of high-density polyethylene reinforced with carbon nanofibers nanocomposite material produced by extrusion techniques have been investigated experimentally. carbon nanofibers (CNFs) have been added into a high-density polyethylene (HDPE) matrix utilizing a twin-screw extruder and compression molding method. High-density polyethylene, which was enhanced with different percentages (0 wt%, 1 wt%, and 2 wt%) of carbon nanofibers, was produced in the form of dog-bone shape, according to D 638-02a ASTM standards and were tested. The increase in tensile strength, Young's modulus of elasticity, and ductility of a material were noted.
