摘要
目的通过准静态压缩试验研究泡沫铝-聚氨酯复合材料(AF-PU)的压缩性能,并利用试验数据探究泡沫铝(AF)相对密度对整体材料吸能性能的影响规律。方法首先使用相关仪器和材料制备AF-PU复合材料,其次用相关仪器对其进行准静态压缩试验。结果AF-PU复合材料通过相关仪器进行准静态压缩试验,计算得到相对应的应力-应变曲线,同时通过计算得到相对应的吸能-应变曲线。当泡沫铝相对密度从5.6%增加到6.7%时,整体复合材料的屈服强度提升了22.18%。在压缩过程中,当复合材料的压缩应变为0.8时,整体复合材料的总吸能增加了70.08%。结论AF-PU复合材料的吸能性能随着AF相对密度的增加而增强。
The work aims to study the compressive properties of aluminum foam-polyurethane(AF-PU)composites through the quasi-static compression experiments,and investigate the rule of effect of relative density of aluminum foams(AF)on the energy absorption properties of the composites.AF-PU composites were first prepared with related instruments and materials,and then the quasi-static compression experiments were carried out with related instruments.The AF-PU composite material was subject to the quasi-static compression experiments by related instruments,the corresponding stress-strain curves were calculated,and the corresponding energy absorption-strain curves were obtained by calculation.When the relative density of aluminum foam increased from 5.6%to 6.7%,the yield strength of the overall composite increased by 22.18%.During the compression process,when the compressive strain of the composite was 0.8,the total energy absorption of the overall composite increased by 70.08%.The energy absorption properties of AF-PU composites intensify with the increase of the relative density of AF.
