Abstract

The aim of this work is to provide a manufacture guide for producing a tailor-made amine-epoxy system that can operate at different services temperatures depending on the post-curing treatment. Therefore, a data set compilation of the mechanical and thermal properties of a commercial thermoset system (Epikure 3223 amine/Epon 828 epoxy) was obtained after exposure to a room temperature cure followed by different post-cures (80, 100, 120 °C), all below the fully cured glass transition temperature (T_g∞ ∼ 153 °C). The mechanical properties of this epoxy system were determined through dynamic mechanical analysis (DMA) and flexural testing, while its thermal behavior was evaluated by differential scanning calorimetry (DSC), thermomechanical analysis (TMA), and thermogravimetric analysis (TGA). The data was analyzed using analysis of variance (ANOVA) to assess if the selected post-curing temperatures provoke a statistically significant difference on the corresponding properties. This data highlights the importance of selecting an adequate post-curing process to extend the temperature range of the glassy state, ensuring reproducible mechanical and thermal properties up to temperatures close to T_g∞, which is key for high temperature applications in automotive, aeronautic, aerospace and construction. Furthermore, this approach guarantees that the curing kinetics would no longer influence the thermal history of this epoxy system.

胺-环氧树脂体系在不同后固化温度下的力学和热性能数据

这项工作的目的是为生产定制的胺-环氧树脂体系提供制造指南，该体系可以根据固化后处理在不同的服务温度下运行。因此，在暴露于室温固化之后，不同的后固化（80、100、120°C），均低于完全固化的玻璃化转变温度（Tg∞~ 153°C），获得了商业热固性体系（Epikure 3223胺/Epon 828环氧树脂）的机械和热性能的数据集汇编。通过动态力学分析（DMA）和弯曲测试确定了该环氧体系的力学性能，并通过差示扫描量热法（DSC）、热力学分析（TMA）和热重分析（TGA）评估了其热行为。采用方差分析（ANOVA）对数据进行分析，以评估所选择的养护后温度是否会对相应的性能产生统计学上显著的差异。这些数据强调了选择适当的后固化工艺以延长玻璃态温度范围的重要性，确保可重复的机械和热性能达到接近Tg∞的温度，这对于汽车，航空，航空航天和建筑中的高温应用至关重要。此外，这种方法保证了固化动力学不再影响该环氧体系的热历史。

期刊介绍： Data in Brief provides a way for researchers to easily share and reuse each other''s datasets by publishing data articles that: -Thoroughly describe your data, facilitating reproducibility. -Make your data, which is often buried in supplementary material, easier to find. -Increase traffic towards associated research articles and data, leading to more citations. -Open up doors for new collaborations. Because you never know what data will be useful to someone else, Data in Brief welcomes submissions that describe data from all research areas.
