Mechanical properties and structural health monitoring performance of carbon nanotube-modified FRP composites: A review

Abstract Fiber-reinforced polymer composites are high-performance materials used extensively in aerospace and defense industries. Researchers have added various nanoscale to FRPs for improving their mechanical properties prepare multifunctional composites. Carbon nanotubes (CNTs) with high strength, modulus, large aspect ratio emerged as a frontrunner the nano-reinforcements, there is volume of published research on this topic. This article provides an extensive review key publications covering topics fabrication methods, enhancement properties, applications CNT-modified FRP structural health monitoring. A description main methods adding CNTs into materials, including dispersion resin film lay-up, presented. focus effect composites, interlaminar fracture toughness, impact resistance, fatigue properties. Since self-sensing potential use nondestructive identification (NDI) monitoring (SHM) composite structures. Finally, discussion problems that might be encountered during nano-reinforcements FRP, future application reported.
