This study explores the load transfer and CNT pull-out mechanisms in aluminum-carbon nanotube (Al-CNT) composites compared to pure aluminum matrix using molecular dynamics (MD) simulation. The results show that Al-CNT composites show a 45% improvement in strength compared to pure aluminum, with a load transfer mechanism enhancing stiffness and strength. The pull-out mechanism, however, only marginally increases strength but exhibits a higher failure strain. The study also highlights that excessive CNT fracture or pull-out can reduce mechanical properties. The findings provide valuable insights into the deformation behavior of Al-CNT composites and offer opportunities for tailoring their properties for specific applications.
