摘　　要：目的设计一种缓冲性能优良的缓冲结构,并评估其填充材料的力学性能。方法把泡沫铝原材料加工成试样尺寸,用钻床给泡沫铝试样钻孔,填入不同体积分数的聚氨酯。采用冲击实验的方法对泡沫铝-聚氨酯复合材料的力学性能进行分析。结果在泡沫铝-聚氨酯复合材料试样中,聚氨酯的体积分数为4.9%时材料韧性最好。结论泡沫铝-聚氨酯复合材料结构的缓冲性能比泡沫铝单体更好,是最理想的抗高冲击、高过载缓冲防护材料。This study aimed to find out a buffer filling material with good cushion performance, and evaluate its mechanical properties. The aluminum foam raw materials were processed into the sample size, and made holes with drilling machine . Then the holes were filled in with different volume percentages of polyurethane. Impact test methods were adopted to analyze the aluminum foam-polyurethane mechanical properties of polyurethane composites. The best results of toughness was found when the proportion of polyurethane in the sample volume percentage was 4.9% Taken together, the cushion properties of aluminum foam-polyurethane with composite structures is better than aluminum foam monomer, which is the best anti-high impact material with high overload protective cushion.
