oIn order to realize the application of continuous glass fibers (GFs) in polyvinyl chloride (PVC), the wet powder impregnation technology was introduced to the preparation of the PVC/GF composites to improve the mechanical properties of the PVC products. During the molding process, the PVC powder impregnated GFs tapes were prepared first and then hot pressed into the test samples. Besides, the effect of the processing conditions, such as molding temperature, molding pressure and dwelling time, on the mechanical properties of the samples were investigated. In addition, the coupling agents and the heat stabilizers were also applied to improve the bonding interface between GFs and PVC and the thermal stability of the composites. The experimental results indicated that the samples prepared with the molding temperature of 160 °C, the molding pressure of 6 MPa and the dwelling time of 10 min could achieve the best mechanical properties. Moreover, the addition of KH550 could greatly improve the bonding interface and the mechanical properties. The applied organotin heat stabilizer also caused a definite improvement in the Vicat softening temperature and the heat deflection temperature of the samples.

为了实现连续玻璃纤维（GFs）在聚氯乙烯（PVC）中的应用，将湿粉浸渍技术引入到PVC / GF复合材料的制备中，以提高PVC产品的机械性能。在模制过程中，首先准备了PVC粉末浸渍的GFs胶带，然后将其热压到测试样品中。此外，还研究了成型条件，成型温度，成型压力和保压时间对样品力学性能的影响。此外，还使用偶联剂和热稳定剂来改善GFs和PVC之间的键合界面以及复合材料的热稳定性。实验结果表明，样品的成型温度为160°C，成型压力为6 MPa，保压时间为10分钟，可以获得最佳的机械性能。此外，添加KH550可以大大改善粘合界面和机械性能。所施加的有机锡热稳定剂还引起维卡软化温度和样品的热变形温度的明显改善。
