摘　　要：双马来酰亚胺(BMI)树脂由于其优异的性能被广泛应用于航空航天等领域,在近些年受到越来越多研究者们的关注。介绍了BMI树脂在使用过程中存在的问题,其中BMI树脂分子链短且存在大量刚性基团使得固化后交联密度大,导致固化物韧性差,成为了制约BMI树脂使用的最大问题。重点介绍了BMI树脂的增韧改性方法,包括二元胺类化合物改性、烯丙基化合物改性、橡胶改性、热塑性树脂改性、热固性树脂改性、无机纳米粒子改性和合成新型BMI等。最后根据现有增韧方法所存在的问题,对未来BMI树脂增韧方向发展提出了展望。Bismaleimide(BMI)resin has been widely used in aerospace and other fields due to its excellent performance and has attracted more and more attention from researchers in recent years.But the traditional BMI resin cannot be directly used due to its poor toughness and high melting point,so it is necessary to be modified.In this paper,the basic situation of bismaleimide resin(BMI)is briefly introduced.The main modification methods of BMI are reviewed,including modification of binary amine compound,allyl compound,rubber,thermoplastic resin,thermosetting resin,nanoparticle modification and synthesis of new BMI.In addition,the views on the future development of BMI are expressed.
