Improving The Mechanical and Electrical Performance Of Composite Laminates By Including Nano-particles: Review Article

These days, researchers have focused on improving the mechanical performance of composite laminates owing to a broad range of their applications in fields like aerospace, military, civil, marine, etc. In this regard, efforts have been made to improve the mechanical and electrical properties of composite laminates by using nanoparticles. For developing high-performance composite laminates, the dispersion of nanoparticles in the composite laminates is significantly important; however, it remains a challenge. This review study focuses on strategies that have been adopted for developing appropriate chemical and physical methods to achieve controlled dispersion of nanoparticles in composite laminates. The effect of nanoparticles on mechanical properties such as tensile and impact strength, compression, and fracture toughness have been discussed thoroughly in this study. Further, this study proves that the addition of conductive nanoparticles to the composite laminates can change their dielectric properties and make them sensors for damage failures during applied loading.
