摘　　要：为了研究多轴向经编涂层织物在拉伸载荷下的变形行为,以0°、90°和±45°衬入高强涤纶工业丝增强四轴向经编织物为基布,在其表面涂覆聚乙烯膜材的新型涂层织物为研究对象。在该材料5个典型方向上进行单轴拉伸试验和不同参数的蠕变试验及蠕变回复试验。由试验数据分析施加应力和织物结构对该材料蠕变变形的影响,通过数学模型得到该材料黏弹性和黏塑性的变形数据。结果显示数学模型与试验数据具有良好的一致性,该数学模型可以被用来预测该涂层布的蠕变行为。In order to study deformation behavior at tensile mode of multi-axial warp knitted fabrics with coating,the new coated fabric used for membrane was made by quad-axial warp-knitted fabric with four directions（0°,90°and ±45°）of high strength polyester.The uniaxial tensile test and a series of creep and strain recovery tests with different parameters were conducted in five directions.The effect of stress and fabric structure on the material’s creep response was studied and the viscoelastic and viscoplastic deformation data from creep and strain recovery test was analyzed via a mathematical model.The results show that the mathematical model is consistent with the experimental data,indicating that the mathematical model can be used to predict the creep behavior of the coated fabrics.
