摘　　要：碳纤维增强树脂基复合材料(CFRP)具有高强高模的优点,被广泛应用于汽车、体育、船舶、航空航天等领域,达到了材料轻量化的要求。目前使用较多的树脂基体以环氧树脂(EP)等热固性树脂为代表,普遍存在脆性大、韧性差的问题,导致复合材料层合板容易在层间发生开裂。层间增韧是一种有效的增韧方式,它可以在不改变基体树脂粘度的情况下对特定区域进行增韧,提高材料的断裂韧性。本文介绍了层间断裂模式并总结了层间断裂韧性(ILFT)测试的数据处理方法,总结了聚合物颗粒与无机纳米颗粒(主要是碳纳米管)的颗粒种类、增韧机制、引入方式,并主要通过层间断裂韧性评价了各种颗粒的增韧效果。Carbon fiber reinforced polymer matrix composite(CFRP)has the advantages of high strength and high modulus,and is widely used in automotive,sports,ships,aerospace and other fields to achieve the requirements of lightweight materials.At present,thermosetting resins such as epoxy resins are the most commonly used resin substrates,which generally have the problems of high brittleness and poor toughness,resulting in the cracking of composite laminates easily in the layers.Interlayer toughening is an effective toughening method,which can toughen specific areas without changing the viscosity of the matrix resin and improve the fracture toughness of the material.This paper introduces the interlayer fracture model and summarizes the data processing method of interlayer fracture toughness(ILFT)test,summarizes the particle types,toughening mechanisms and introduction methods of polymer particles and inorganic nanoparticles(mostly carbon nanotubes),and evaluates the toughening effects of various particles mainly by interlayer fracture toughness.
