Woven fabric polymer composites, owing to their ease of formability along with a combination of light weight and high strength, have found considerable attention in several leading industries including aerospace, automotive, construction, marine, and energy. Despite this wide interest, there still exists a lack of knowledge and standardization in testing and analyzing their mechanical responses under complex loading conditions. More specifically, basic material deformation mechanisms such as fiber tension and fabric trellising have been mostly studied under individual modes, and there is less information on the complexity of fabrics behavior under combined loading modes such as simultaneous biaxial tension and shear. Examples of such deformation modes in practical applications include the use of a blank-holder during stamping, and the loading and unloading of inflatable beams made of bidirectional woven fabric composites.

机织聚合物织物复合材料由于其易于成型以及轻质和高强度的结合，在航空航天、汽车、建筑、海洋和能源等几个主要行业得到了相当大的关注。尽管有了广泛的兴趣，但在测试和分析其在复杂载荷条件下的力学响应方面仍然缺乏知识和标准化。更具体地说，基本的材料变形机理，如纤维拉伸和织物网格化，大多是在单独的模式下进行研究的，而关于织物在同时双向拉伸和剪切等组合加载模式下行为的复杂性的信息较少。这种变形模式在实际应用中的例子包括在冲压过程中使用压边机，以及双向机织复合材料制成的充气梁的加载和卸载。
