| 摘要: |
| 对新型有机—无机杂化纳米材料多面体低聚硅倍半氧烷(POSS)改性AFG-90环氧树脂体系前后的粘度变化进行研究，并根据双Arrhenius方程建立了与试验数据较为符合的化学流变模型，同时以此模型对改性树脂体系RTM工艺性能进行评估。 |

| Abstract: |
| Chemo-rheological of AFG-90 epoxy resin modified with new organic-inorganic hybrid nano-materials POSS was studied in this paper. A rheological model based on dual-Arrhenius equation was established and used to simulate chemo-rheological behavior of this resin system. The estimated viscosity of the model was in good agreement with that of the experiment in the initialization reaction stage. The processing window of the resin system can be well determined based on the rheological model. |
