摘　　要：制备了系列Ti O2粒子(M系列粒子)改性氰酸酯树脂(CE)基复合材料,讨论了复合材料的固化动力学、动态热力学性能,分析了复合材料微观形貌变化与性能提升之间的联系。结果表明,M系列粒子的引入,在降低复合材料活化能,有利于复合材料固化成型的同时,未改变复合材料的固化机理。当M2粒子含量为4%时,复合材料的储能模量增幅为60%,玻璃化转变温度增幅为12%。Series of titanium dioxide particles（M-series particles） modified cyanate ester resin（CE） based composites were prepared.The curing kinetics and dynamic mechanical properties were discussed and the relationships between properties and microstructure were analyzed.The results show that the introduction of the M-series particles in composites reduce the activation energy and is conducive to composites cure,while the composites curing mechanism is not changed.The composites with M-series particles of 4%,the storage modulus and loss modulus of the composites were improved,the glass transition temperature and storage modulus are increased by 12% and 60%.
