| 摘 要： | 用渗流法向开孔泡沫铝-硅合金和泡沫纯铝中充填硅橡胶获得含硅橡胶的泡沫材料, 在材料试验机和SHPB上对含硅橡胶的复合材料进行动态与准静态压缩实验。实验结果表明:含硅橡胶的泡沫复合材料只有弹性段和塑性段两个阶段，具有更高的应变率敏感性，其应力-应变曲线抖动幅度比较大。

| Abstract: | The aluminium foam containing silicone rubber was fabricated by infiltrating silicone rubber into the open-cell aluminum foam. The dynamic compressive experiments and quasi-static experiments were conducted on material test system and SHPB, respectively. The results show that the compressive stress-strain curves of the composites of aluminium foam containing silicone rubber are characterized by two distinct regions, i. e. elastic region and plateau region; and are more sensitive in strain rate, and larger oscillation in compression curve. |
