COMPRESSIVE BEHAVIOR OF CARBON NANOTUBE REINFORCED POLYPROPYLENE COMPOSITES UNDER HIGH STRAIN RATE: INSIGHTS FROM MOLECULAR DYNAMICS

Since the discovery of carbon nanotubes (CNTs), they have received a lot attention because their unusual mechanical electrical properties. Strain rate is one key factors that plays vital role in enhancing properties nanocomposites. In this study, (4, 4) armchair single-walled nanotube (SWCNT) was employed with polymer matrix as polypropylene (PP). The influence compressive strain on SWCNT/PP nanocomposites evaluated using molecular dynamics simulations, and been predicted. Stone-Wales (SW) vacancy defects were integrated SWCNT. maximum Young's modulus (E) 81.501 GPa found for pristine composite 10<sup>10</sup> s<sup>-1</sup>. least value E 45.073 6% SW defective/PP 10<sup>8</sup> While defective CNT/PP showed lowest 39.57GPa It decrease increase percent defect. also seen enhanced increment applied rate. results obtained from study could be useful researchers designing PP-based materials compression loading to used biomedical applications.
