提出了一种新的三维中空结构机织物的设计方法，并研究了蜂窝尺寸对织物增强聚氨酯弹性体复合材料缓冲性能的影响。从横截面的角度分析了织物的结构，以织物层数和蜂窝尺寸为参数，提出了经纬纱的理论方程。采用提花织机织造了9种不同层数、不同孔尺寸的织物，并用聚氨酯弹性体增强得到织物复合材料。讨论了蜂窝尺寸对织物复合材料缓冲性能的影响。结果表明，随着蜂窝尺寸的增大，蜂窝织物复合材料的抗压性能降低。此外，在65%的应变和加载过程中吸收的能量的应力增加与细胞尺寸减小。压缩回弹性也随泡孔尺寸的变化而变化。结果表明，泡孔尺寸对织物复合材料的缓冲性能有重要影响，可根据其用途作为缓冲材料的设计参数。
In this study, a new design method for a three-dimensional hollow structure woven fabric was proposed and the effect of cellular size on the cushioning property of the fabric-reinforced polyurethane elastomer composite was investigated. The fabric structure was analyzed from a cross-section view and the theoretical equations for the warp and weft yarns were proposed, using the fabric layer and cellular size as parameters. Nine kinds of fabrics with different layers and cellular size were fabricated with a Jacquard loom and reinforced with polyurethane elastomer to yield fabric composites. Then the effect of cellular size on the cushioning property of the fabric composites was discussed. The results showed that upon increasing the cellular size, the cellular fabric composite exhibited lower compression resistance. Moreover, the stress at a strain of 65% and the energy absorbed in the loading process were increased with decreasing cellular size. Moreover, the compression resilience was also changed with the cellular size. It can be concluded that the cellular size had an important effect on the cushioning property of the fabric composite, which can be considered as a design parameter for cushion material based on its usages.
