Abstract:The paper introduces the methods of the toughening modification cyanate ester resin in recent years,
including the nanoparticles(SiO2,SiC) modification,polyhedral oligomeric silsesquioxane(POSS) modification, ther鄄
mosetting resin( EP, BMI) modification, thermoplastic resin modification and other modification methods, then the
toughening mechanism was discussed
