【摘要】 为了掌握HD03树脂固化过程中粘度与温度的关系,实现对以该树脂为基体材料的先进复合材料结构制造工艺过程的监测、控制与优化,利用两种粘度测试仪器测定了HD03树脂在不同温度范围内的温度变化,并就贮存时间对树脂粘-温关系的影响进行了试验与讨论。实验结果表明,该种树脂的粘-温关系符合阿累尼乌斯公式,该种树脂的加压点应选择在120～130℃之间,贮存时间对树脂粘-温关系有重要影响。更多还原

【Abstract】 To monitor, control and optimize the cure process of composites with HD03 epoxy resin as matrix, it is essential to investigate its viscosity-temperature relationship. In this presentation, viscosity-temperature relationship of HD03 epoxy resin was measured by two different apparatus in different temperature ranges and meaningful results were obtained. Influence of storage time on the viscosity-temperature relationship is also tested and discussed in this paper. It is found that the viscosity relationship of HD03 is agreed with Arrhenins’s law; composite laminates with this kind of resin as matrix should be pressed in the temperature range of 120～130℃; storage time can significantly influence the viscosity profile of resin.更多还原
