High-Energy Impact Behaviors of Concrete Structures Strengthened with Multi-Walled Carbon Nanotube Composites

This study analyzed high-energy impact behaviors of concrete structures strengthened with multi-walled carbon nanotube (MWCNT) composites. The proposed multi-walled carbon nanotubes demonstrated excellent mechanical properties such as high stiffness, high strength, and improved elongation. These distinctive properties allow the use of the product in several high-performance applications. Using a multi-scale analysis, we investigated the impact mechanism of an MWCNT-reinforced concrete structure using various parameters. The parametric studies focused on the various impact effects on structural performance. In addition, a three-dimensional simulation was carried out for the verification of our experimental results.
