摘要/Abstract

摘要： 研究了一种新型的用于真空辅助树脂传递模塑成型工艺(VARTM)酚醛树脂的流变特性。根据实测等温粘度曲线,采用双阿累尼乌斯模型, 建立了用于真空辅助树脂传递模塑成型工艺(VARTM)酚醛树脂的化学流变特性模型方程,分析表明模型拟合与实验结果之间具有较好的一致性,这为有效地预测RTM树脂的低粘度工艺窗口、合理制定复合材料成型工艺参数提供了必要的科学依据。

Abstract: A new kind of phenolic resol resin named Z615101, was developed for vacuum assisted resin transfer molding process (VARTM). The resin has the advantages of higher char yield, lower initial viscosity and longer pot life of the process as compared to conventional phenolic resol resin. It is suitable for manufacturing advanced fiber-reinforced composite materials ranging from smallarticles of simple shape, to large articles with complex shape and high structural performance characteristics, especially large complex three-dimensional part of advanced composite materials for aerospace application. The rheological behavior of phenolic resol resin was studied. The curve of dynamic viscosity-temperature for Z615101 was also studied. The Arrhenius viscosity equation was established based on the measured isothermal viscosity curves. Analysis results indicated that the model values were in good agreement with the experimental results. The optimal processing temperature window was between 70~80 ℃ learned from the isothermal viscosity curves, which were established on the basis of model equation and would provide the theoretical foundation for the actual VARTM processing molding.

Key words: phenolic resol resin, VARTM processes, chemical rheological behavior, composites, proce-ssing window
