摘要

目的:研究聚氨酯泡沫/蜂窝纸板复合材料在静压缩试验中的力学行为和吸能能力。方法:采用电子万能试验机对聚氨酯泡沫/蜂窝纸板复合材料进行静态压缩试验。分析了复合材料在静压缩条件下的力学行为,以及影响复合材料静缓冲性能的因素。然后,对复合材料和简单材料的吸能能力进行了比较。结果:填充聚氨酯后泡沫/蜂窝纸板的屈服应力、强度等指标提高了一倍。孔径大小是影响复合材料静缓冲性能的主要因素。结论:复合材料的能量吸收量约为两种简单材料总能量的1.85倍。

Research on Static Compression Test of Polyurethane Foam/Honeycomb Paperboard Composite Material
Objective: To study the mechanical behavior and energy absorption ability in the static compression test of polyurethane foam/Honeycomb paperboard composite material. Methods: The static compression test of polyurethane foam/honeycomb paperboard composite material are conducted by electronic universal testing machine. The mechanical behavior under the conditions of static compression and the influence factors of composite material static cushioning properties were analyzed. Then, a comparison was made between composite materials and simple materials in the respect of the energy absorption ability. Results: The yield stress, strength and other indicators of foam/honeycomb paperboard have doubled growth after filling polyurethane. The aperture size is the main influence factor of static cushioning properties of composite material. Conclusion: The energy absorption amount of composite materials is about 1.85 times than the total energy of two simple materials.
