Abstract: Continuous fiber reinforced composite is widely used in aerospace and other fields due to its advantages of light weight and high strength. The main ways to improve the interlaminar strength of composite are improving the performance of resin matrix, increasing the normal material and interlaminar toughening. Interlaminar toughening is a kind of method which embeds fibers, particles and thin films as reinforcing phases into the interlaminar of continuous fiber composite to achieve the interlaminar strengthening effect, it does not need to change the existing process. The process is easy to realize, and the reinforcement effect is obvious. Considering the cost, technical difficulty and other factors, the interlaminar toughening method is a feasible and effective interlaminar strengthening method. In this paper, the latest research progress of interlaminar toughening technology of fiber-reinforced composite is reviewed. The research of interlaminar toughening technology of composite is divided into fiber interlaminar toughening, nano material interlaminar strengthening, particles interlaminar toughening, film interlaminar toughening, etc, which can provide support for improving the interlaminar strength of fiber-reinforced composite and the wider application of fiber-reinforced composite.
