以下请结合图1和图2，一实施方式的凝胶复合材料的制备系统10，包括浸胶平台100及移动浸胶机构200。
浸胶平台100具有工作台面110。移动浸胶机构200包括固定座210以及设在固定座210上的第一放卷装置220、浸胶装置230、第二放卷装置240、第三放卷装置250、第一复卷装置260及第二复卷装置270。固定座210能够沿浸胶平台110往复移动，第一放卷装置220用于放卷待浸胶的增强体22以使待浸胶的增强体22平铺在工作台面110上，浸胶装置230用于将预制溶胶30引导至平铺在浸胶平台100上的待浸胶的增强体22上，第二放卷装置240用于将覆盖载体40铺在浸胶之后增强体24的上表面，第三放卷装置250用于在凝胶化的增强体26的下表面所在的一侧将间隔载体50放卷在增强体26的下表面，第一复卷装置260用于卷绕回收覆盖载体40，第二复卷装置270用于卷绕一侧覆盖有间隔载体50的凝胶化的增强体26。

再进一步，热水容器235与换热器236连通的循环管道上还设有循环控制 阀238。循环控制阀238用于控制流经换热器236的热水流量，进而可以控制出胶管道232中预制溶胶30的温度。优选的，在靠近出胶管道232的出胶端设有温度检测传感器239，该温度检测检测传感器239与循环控制阀238连接，从而可以通过实时检测的预制溶胶30的温度数据来调整循环控制阀238的开启程度。
通过对浸胶装置230设置加热部件，可以对预制溶胶30进行加热，加热至一定温度后的预制溶胶30的反应速度会加快，进而有利于加快预制溶胶30的凝胶化的进程，提高生产效率。
