摘　　要：连续纤维增强复合材料因轻质、高强等优点被广泛应用于航空航天等领域,提高复合材料层间强度的方式主要有改善树脂基体性能、增加法向材料和层间增韧等。层间增韧方法是一种将纤维、颗粒及薄膜等作为增强相嵌入连续纤维复合材料层间,以达到层间增强效果的方法。采用层间增韧方法无须改变现有的工艺方法,实现过程容易,并且增强效果明显。综合成本、技术难度等方面因素,层间增韧方法为一种切实可行、效果明显的层间增强方法。本文综述了纤维增强复合材料层间增韧技术的最新研究进展,将复合材料层间增韧技术的研究分为纤维层间增韧、纳米材料层间增韧、颗粒层间增韧、薄膜层间增韧等,可为提升纤维复合材料层间性能及纤维复合材料得到更广泛的应用提供支撑。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.
