| Popis: | 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. |
