The impact of water-induced degradation on the mechanical properties of the chosen two PTFE-coated, glass threads woven fabrics is investigated in this paper. The paper begins with a survey of literature concerning the investigation and determination of coated woven fabric properties. The authors carried out the uniaxial tensile tests with an application of flat and curved grips to establish the proper values of the ultimate tensile strength and the longitudinal stiffness of groups of specimens treated with different moisture conditions. Despite the water resistance of the main materials used for fabrics manufacturing, the change of the mechanical properties caused by the influence of water immersion has been noticed. The reduction in the tensile strength resulting under waterlogged is observed in the range from 5% to 16% depending on the type of investigated coated woven fabric and direction of weft or warp.
本文研究了水致降解对所选两种聚四氟乙烯涂层玻璃丝机织物力学性能的影响。本文开篇对有关涂层机织物性能研究与测定的文献进行了综述。作者采用平夹和曲夹进行单轴拉伸试验，以确定不同湿度条件处理的各组试样的极限抗拉强度和纵向刚度的合适值。尽管用于织物制造的主要材料具有防水性，但已注意到水浸影响导致的力学性能变化。根据所研究的涂层机织物类型以及纬向或经向方向，浸水后观察到抗拉强度降低了5%至16%。
