目的 研究得到丝瓜络材料的静态缓冲系数与最大应力曲线，为应用丝瓜络作为缓冲材料的计算提供理论依据与实验数据。方法 参考GB 8168—1987包装用缓冲材料静态压缩试验方法，在电子万能实验机上测试不同分组样件，研究受力方向、尺寸、湿度、结构等因素对缓冲性能的影响，以及该材料与其他缓冲材料（聚脂海绵、瓦楞纸板）静态缓冲性能的对比。结果 得到了丝瓜络材料力-位移曲线与应力-应变曲线，并计算得到了缓冲系数-最大应力曲线。结论 丝瓜络是缓冲性能优越、环保的自然材料，可完全降解。完整的丝瓜络圆柱体纵向受压时的缓冲性能与瓦楞纸板结构以及蜂窝纸板结构类似，丝瓜络单层外壁材料可重叠横向受压，其缓冲性能与聚脂海绵类似，在大载荷情况下优于聚脂海绵。去除内芯的丝瓜络缓冲性能优于完整的丝瓜络圆柱，丝瓜络代替其他缓冲材料完全可行。

The work aims to obtain the static C-δm curves of luffa sponge materials by research, to provide theoretical basis and experimental data for the calculation of the luffa sponge used as the cushion material. GB 8168—1987 testing method of static compression for package cushion materials was referred to. Different groups of specimens were tested on the electronic universal tester. The influence of such factors as force direction, size, humidity and structure on the cushion materials was studied. The static cushion properties of such materials and other cushion materials (polyester sponge and corrugated paperboard) were compared. The force-displacement curves and the stress-strain curves of the luffa sponge materials were obtained, and the C-δm curves were obtained by calculation. As a natural material featured by excellent cushion property and environmental protection, luffa sponge can be completely degraded. The whole luffa sponge cylinder has the similar cushion property as corrugated paperboard and honeycomb paperboard when it is under load along the axis. The single-layer outer wall material of luffa sponge can be overlapped and laterally loaded. In this case, it has the similar cushion property as polyester sponge, even better when under larger load. The cushion property of the luffa sponge with inner core removed is superior to the whole luffa sponge cylinder. It is completely feasible to replace other cushion materials with luffa sponge.
