摘　　要：氰酸酯树脂具有高耐热性、优异的介电性能及良好的加工性等,可用于高性能透波材料、航空航天结构材料和隐形航空器等领域。但是,氰酸酯树脂的韧性较差和制造成本高等缺点,限制了其使用范围。在介绍氰酸酯树脂的结构和性能的基础上,综述了氰酸酯树脂的改性方法,主要包括无机刚性填料改性、橡胶改性、热塑性树脂改性、热固性树脂改性等方法,并介绍了各种增韧机理、特点及存在的问题,指出了今后的研究方向。Cyanate ester resins (CE) have become a new and unique class of high-performance thermosetting resins for being used as advanced matrices in both electronic and aerospace industries. CE possesses many advantages including high mechanical properties, good resistant-flammability characteristics, excellent electrical properties and good processability. But its applications are limited because of its brittle in nature and high manufacturing cost. In this paper, the methods to improve toughening of CE, including inorganic particles, rubbers, thermoplastics and thermosets as additives are introduced. In addition, the mechanisms, characteristics and problems in each method of toughening of CE are summarized, and the tendency of studying toughening of CE is predicted.
