| 摘 要： | 通过示差扫描分析法(DSC)研究了SiO2/氰酸酯树脂(CE)/含有活性稀释剂的双马来酰亚胺树脂(BMI)复合材料的固化动力学,求得其固化工艺参数为:凝胶温度87.13℃,固化温度137.27℃,后处理温度203.58℃;用Kissinger法和Ozawa法求得其固化动力学参数为:表观活化能6.692kJ/mol,反应级数1.493,Arrhenius方程中的频率因子11.9445s-1。与CE/BMI体系对比表明,SiO2的加入可以降低CE/BMI体系的活化能,使其固化反应可以在较低温度下进行。

| Abstract: | The curing kinetics of SiO2/cyanate ester(CE)/bismaleimide with diluent agent(BMI) composite was studied by differential scanning calorimetry(DSC).The curing process parameters were obtained as follews:gel temperature 87.13 ℃,curing temperature 137.27 ℃ and post-treating temperature 203.58 ℃.The parameters of the curing kinetics were calculated by Kissinger and Ozawa methods.The activation energy of the system was 6.692 kJ/mol.The reaction order was 1.493 and the frequency factor of the Arrhenius equation was 11.9445 s-1.Compared to the CE/BMI system,the results indicated that the addition of SiO2 could lower the activation energy of the CE/BMI system and the curing reaction could occur at a relative low temperature. |
