In this study, a kind of honeycomb-structured woven fabric was investigated and the effect of yarn size and fabric layer on the compression property of the fabric-reinforced polyurethane elastomer composites was discussed. The honeycomb-structured fabric was analyzed from the cross-sectional view of combined regular hexagonal cells. The three-layer fabric and four-layer fabric were designed and fabricated using three different finenesses of weft yarns. After that, polyurethane elastomer was used as matrix resin and the 3D honeycomb-structured fabrics were composited. In-plane compression test was conducted to investigate the cushioning property. For samples with doubled weft yarns, such as 3L-2W, the stress value when compressed to 65% of its initial thickness (CV_65%), energy absorption (EA), and specific energy absorption (SEA) showed higher values than 3L-1W and 3L-1.5W. It was concluded that the weft yarn fineness had an important effect on the compression property of fabric composites. The thicker yarn size, the stronger cell wall, and the lightweight honeycomb-structure composite was difficult to be compressed. As to the fabric layers, three-layer composites showed a higher compression property than four-layer ones. The reason for this was considered to be the fiber volume content, which was the key parameter affecting composite mechanical properties. As the real fiber volume content in a three-layer fabric composite was higher than that of a four-layer fabric composite, it was resulted in a higher allowable safe stress and energy absorption ability. It can be concluded that the yarn fineness and fabric layers had an influence on the compression property, which can be seemed as the design parameters of honeycomb-structured fabrics for cushion applications.

在这项研究中，研究了一种蜂窝结构的机织物，并讨论了纱线尺寸和织物层对织物增强聚氨酯弹性体复合材料压缩性能的影响。从组合正六边形单元的截面图分析蜂窝结构织物。三层织物和四层织物使用三种不同细度的纬纱设计和制造。之后，以聚氨酯弹性体为基体树脂，复合出3D蜂窝结构织物。进行面内压缩试验以研究缓冲性能。对于具有双纬纱的样品，例如 3L-2W，压缩至其初始厚度的_65% (CV _65%)时的应力值)、能量吸收 (EA) 和比能量吸收 (SEA) 显示出高于 3L-1W 和 3L-1.5W 的值。得出的结论是纬纱细度对织物复合材料的压缩性能有重要影响。更粗的纱线尺寸、更强的细胞壁和轻质的蜂窝结构复合材料难以被压缩。至于织物层，三层复合材料比四层复合材料表现出更高的压缩性能。其原因被认为是纤维体积含量，这是影响复合材料力学性能的关键参数。由于三层织物复合材料的实际纤维体积含量高于四层织物复合材料，因此具有更高的许用安全应力和能量吸收能力。
