摘要: 为探究织物表面处理对涤纶织物/聚氯乙烯(PVC)复合材料界面黏结性能的影响,文章采用不同处理方法得到了三种不同表面性质的涤纶织物,通过接触成型技术制备了涤纶织物/PVC复合材料,并对复合材料的动态机械性能和剥离强度进行分析。研究发现,涤纶织物的表面性质对涤纶织物/PVC复合材料界面性能有显著影响,三种复合材料的阻尼因子的峰值分别为0.53、0.49、0.40,剥离强度的的平均值分别为0.408、0.537、0.663 N/mm。復合材料动态机械性能的分析结果与剥离强度具有很好的一致性。

Abstract:
In order to investigate the effect of surface treatment on the interfacial bonding properties of polyester fabric/PVC composites, three kinds of polyester fabrics with different surface properties were obtained by using different treatment methods. The contact molding technology was used to prepare polyester fabric/PVC composites, and the dynamic mechanical properties and peeling strength of composites were analyzed. It was found that the surface properties of polyester fabric had a significant impact on the interfacial properties of polyester fabric/PVC composites. The peaks of damping factors of the three composites were 0.53, 0.49 and 0.40, respectively. The average peeling strength of the three composites were 0.408, 0.537, 0.663 N/mm, respectively. The analysis results of dynamic mechanical properties of the composites were in good agreement with the peeling strength.

涤纶织物/聚氯乙烯(PVC)柔性复合材料是20世纪中后期出现的一种新型结构复合材料。它具有质量轻、强度高、施工速度快等优点,被誉为“21世纪现代绿色建筑材料”[1-2]。涤纶织物/PVC柔性复合材料在实际应用中经常会受到很多因素的影响,比如季节轮回引起环境温度的变化,风力作用引起载荷大小的变化,从而发生疲劳、破坏。因此,为了更加合理和实用的设计,研究涤纶织物/PVC柔性复合材料的机械性能十分必要。
当前研究人员对涤纶织物/PVC柔性复合材料的机械性能方面取得了重大进展,包括基本力学性能、界面黏结性能、耐久性能等。……
