In this study, the effect of curing applied to jute woven fabric (four-layers) reinforced composite materials in which different proportions of acrylated epoxidized soybean oil (AESO) and epoxy resin are used as matrix material, on the thermal, thermo-mechanical and morphological properties of the composite materials are investigated. Composite material production is carried out by vacuum infusion method, whereas curing at 90 °C is done during production and post-curing at 120 °C is performed using a conditioning oven after production. Dynamic mechanical analysis (DMA) results show that the storage and loss modulus values of composite materials increase with increasing AESO ratio, while tan delta curves display that the bonds between the fiber and matrix of hybrid samples are stronger than composite materials using a single type of resin. This result is also supported by scanning electron microscope (SEM) images. The effect of curing (90 °C) and post-curing (120 °C) temperatures on the thermo-mechanical properties of the composite material is more clearly seen in epoxy composite samples whose glass transition temperature is higher than the room temperature. Besides, the decrease in glass transition temperature of the material with the increase in AESO content is obtained from both DMA and differential scanning calorimetry (DSC) plots.

本研究以不同比例的丙烯酸酯化环氧大豆油 (AESO) 和环氧树脂为基体材料, 固化应用于黄麻机织物 (四层) 增强复合材料, 对热力学、热力学和力学性能的影响。研究了复合材料的形貌特性。复合材料生产采用真空灌注法，生产过程中进行90°C固化，生产后使用调节炉进行120°C后固化。动态力学分析 (DMA) 结果表明，复合材料的储能模量和损耗模量值随着 AESO 比的增加而增加，而 tan delta 曲线显示，混合样品的纤维和基体之间的结合比使用单一类型的复合材料更强。树脂。这一结果也得到了扫描电子显微镜 (SEM) 图像的支持。在玻璃化转变温度高于室温的环氧复合样品中，固化 (90 °C) 和后固化 (120 °C) 温度对复合材料热机械性能的影响更为明显。此外，材料的玻璃化转变温度随着 AESO 含量的增加而降低，可以从 DMA 和差示扫描量热 (DSC) 图中获得。
