Abstract

The interlaminar mechanical properties of composites are important parameters for the application of laminates, and many scholars have applied carbon nanotubes (CNTs) as a promising solution to alleviate the delamination of laminates owing to its excellent mechanical properties and resin compatibility. The types of CNTs and their spatial distribution state in laminates can significantly affect the final interlaminar shear strength (ILSS) and fracture toughness of the laminates. In this paper, the methods of introducing CNTs into laminates are summarized, the techniques and methods for controlling the key parameters of CNTs such as dispersion, distribution and orientation of CNTs in laminates are reviewed. And then, these parameters of CNTs on ILSS and fracture toughness were discussed. It was found that CNTs with small diameters had more advantages in improving interlaminar mechanical properties because they easily penetrated the reinforced fabric. Moreover, CNTs distributed vertically along the thickness direction can improve the interlaminar mechanical properties of composites to a greater extent. Furthermore, through comprehensive comparison, we found that chemical vapor deposition method, interlayer insertion and surface assembly can significantly improve the mode I interlaminar fracture toughness, while the resin mixing and prepreg modification can greatly improve the mode II interlaminar fracture toughness. In addition, CNTs local filling technology can achieve the purpose of local performance improvement for composite components. Finally, the current issues and potential opportunities of the carbon fiber-reinforced laminates filled with CNTs are pointed out, and new directions for future prospects are proposed.
