Optimizing the Mechanical Properties of Carbon Nanotube-Reinforced Metal Matrix Composites: A Comparative Study of Finite Element and Semi-Empirical Approaches

Article scientifique 2025 Autre

Résumé

This study analyzes the mechanical properties of Carbon Nanotube (CNT)-reinforced Metal Matrix Composites (MMCs) using a novel integration of Finite Element Analysis (FEA) and semi-empirical modeling, in order to evaluate the influence of CNT chirality, volume fractions, and lengths on longitudinal, transverse, and shear moduli, through a three-dimensional Representative Volume Element (RVE). The results reveal significant stiffness improvements of up to 76% for aluminum-based composites, especially those containing zigzag CNTs. A comparative analysis between FEA and Halpin-Tsai-based semi-empirical models reveals key modeling assumptions. This work advances the design of high-performance CNT-MMCs for use in the aerospace, automotive, biomedical, and energy sectors.
