摘要
苯并噁嗪树脂是一种适宜RTM工艺的新型耐烧蚀开环聚合酚醛树脂,本工作对该树脂的流变特性进行研究。在粘度实验和DSC热分析实验的基础上,依据双阿累尼乌斯方程建立了与实验数据较为吻合的化学流变模型。模型可揭示树脂在不同工艺条件下的粘度变化规律,定量预报树脂的低粘度平台工艺窗口,为该树脂RTM工艺窗口的确定以及RTM工艺参数优化提供了的科学依据。
Benzoxazine resin is a new ablative ring-opening polymerization phenolic resin for resin transfer molding（RTM）. The rheological behavior of benzoxazine resin is studied with DSC analysis and viscosity experiments. A rheological model based on the dual-Arrhenius equation which is in good agreement with the results of experiments is established and used to simulate the rheological behavior of benzoxazine resin. The processing window of benzoxazine resin can be well determined based on the developed model. The rheological model is important for processing window forecast and processing parameter optimization.
