摘要:
为了得到经编织物膜材在高温下的拉伸力学性能,以典型经编织物膜材PVDF Shelter-Rite#9032为研究对象,进行了5种温度(10、25、50、75、100 ℃)下的单轴拉伸性能试验及破坏后试样截面电镜扫描测试,系统分析了膜材强度、刚度、变形及破坏形态特征随温度变化规律.研究结果表明,高温可明显弱化组分材料强度、刚度及组分界面间变形协调能力,随温度升高膜材应力-应变曲线的初始线性段范围减小且其后续特征段刚度及抗拉强度降低显著,其中与10 ℃时相比,100 ℃时膜材Ⅲ阶段纬向刚度及抗拉强度的降幅分别可达50.64%与39.78%.各温度下经向刚度随应变均呈现出降-升-降的S形特征,而纬向因纱线拉伸变形历程中存在卷曲伸展阶段,配合材料的高温效应,其刚度曲线表现出S形到M形的转变特征.温度升高使得基体塑性变形能力增强、纱线与基体间应力集中效应减弱,断口呈现出粗糙化及纱线抽出特征,100 ℃时基体和纱线层间黏结被严重削弱,端部出现明显脱黏与滑移现象.
Abstract:
To obtain the tensile mechanical properties of warp-knitted fabrics at high temperatures, a series of uniaxial tensile tests at 10, 25, 50, 75 and 100 ℃ and sectional electron microscopy scan of the sample after destruction were performed on a typical warp-knitted composite fabrics, i.e., PVDF Shelter-Rite#9032. The variations of strength, stiffness, deformation, and failure morphology of the studied material at different temperatures were systematically analyzed. The results show that the strength and the stiffness of the component materials, and the interfacial deformation coordination ability are significantly weakened at the high temperature. With the increase of the temperature, the range of the initial linear section of the material stress-strain curve decreases, and the stiffness and the tensile strength of the subsequent characteristic sections decrease significantly. Compared with those at 10 ℃, the weft stiffness and the weft tensile strength of the membrane material in stage Ⅲ at 100 ℃ can be reduced by 50.64% and 39.78%, respectively. The warp stiffness, at each temperature, exhibits a down-up-down S-shaped characteristic with the strain, and when the weft yarn has a stage from curl to straight in the deformation process, the weft stiffness curve shows the transition characteristics from S shape to M shape. The plastic deformation ability of the substrate is enhanced, and the stress concentration effect between the yarn and the substrate is weakened with the increasing temperature, and the fracture of the sample exhibits roughness and yarn pull-out characteristics. The bond between the substrate and the yarn of the composite fabric is severely weakened at 100 ℃, and there are obvious peeling and slipping debonding phenomena at the clamping end of the composite fabric during the tests.
