Development and Behavior Analysis of CNT Fibers Reinforced High-Density Polyethylene Composite via Compression Mold Route

High-density polyethylene (HDPE) composites are widespread in applications such as root barriers and corrosion production pipelines due to their better chemical strength, durability, and fatigue resistance. This investigation will prepare the HDPE composite embedded with 0, 5, 10, 15, and 20 volume percentages (vol%) of carbon nanotubes via compression mold technique with the applied compressive force 100 MPa. The fabricated composite's tensile and impact strength and elongation percentage are investigated based on ASTM standards. Thus, the HDPE with 20 vol% of CNT fiber indicates the maximum tensile and impact strength of 56.3 ± 0.3 MPa and 14.8 ± 0.1 J/mm² and elongation behavior of 148%. It is higher than the other composite prepared by compression molding. The optimum behavior of composite containing various compositions of polypropylene CNT fiber reinforced with 20% volume is recommended for lightweight and automobile applications.
