摘要

目的通过热老化试验,摸清树脂后固化效应及老化规律,探究P580-TM-191RS树脂存在后固化效应持续时间的预测方法,创新性地提出通过分段计算后固化效应持续时间和树脂老化降解持续时间的方法预测常温贮存寿命。方法根据材料的热分析结果设计加速老化试验,以弯曲强度为材料性能评价指标求出不同应力下的树脂性能变化模型,建立设定性能指标下试验时间与试验温度的回归模型,进而外推预测贮存温度条件下树脂的后固化效应持续时间。结果 P580-TM-191RS树脂在室温及多种热环境下均表现出显著的后固化特性,通过建立设定性能指标下试验时间与试验温度的回归模型,外推预测常温条件下树脂后固化效应持续时间约23.5 a。结论针对存在后固化效应树脂,提出的分段计算后固化效应和老化降解持续时间预测常温贮存寿命的方法,经试验验证和相似材料对比验证,该方法较为合理可靠。

Abstract

The work aims to investigate the post-curing effect and aging mechanisms of the resin through thermal aging tests, explore prediction methods for the duration of the post-curing effect of P580-TM-191RS resin, and innovatively propose a phased-calculation approach to predict ambient-temperature storage life by segmentally calculating the duration of the post-curing effect and the aging degradation time of the resin. Based on the thermal analysis results of the material, accelerated aging tests were designed. Flexural strength was used as the material performance evaluation index to determine the performance change models of the resin under different stresses. Regression models were established between the test time and temperature under set performance indices, and the duration of the post-curing effect of the resin under storage temperature conditions was predicted by extrapolation. P580-TM-191RS resin exhibited significant post-curing characteristics at room temperature and under various thermal environments. By establishing regression models between test time and temperature under set performance indices, the duration of the post-curing effect of the resin under room temperature conditions was predicted to be approximately 23.5 years. For resins exhibiting post-curing effects, a method for predicting ambient-temperature storage life by segmentally calculating the duration of post-curing effects and aging degradation has been proposed. This method has been validated through experiments and comparative verification with similar materials, demonstrating reasonableness and reliability.
