摘要

The growing use of composite materials such as carbon fiber-reinforced plastics (CFRPs) and glass fiber-reinforced plastics (GFRPs) in the automotive industry has enabled significant improvements in weight reduction, mechanical strength, and corrosion resistance. Despite these advantages, composites remain vulnerable to impact, fatigue, and environmental degradation, which can compromise safety and service life. Self-healing nanocomposites offer a promising solution by autonomously repairing microcracks and defects, thereby extending durability and reducing maintenance costs. Incorporation of advanced nanomaterials, including nanoparticles, nanofibers, and nanocapsules, further enhances healing efficiency. In addition, structural health monitoring systems enable real-time damage detection and proactive maintenance through techniques such as fiber optic sensing, electromechanical impedance, ultrasonic methods, and wireless networks. This review highlights the synergy between self-healing nanocomposites and SHM technologies, emphasizing their potential to deliver intelligent, resilient, and sustainable automotive materials that advance vehicle safety, performance, and longevity.
