Dynamic compressive behavior of 2 kinds of Al/Teflon reactive materials samples are analyzed by using the Split Hopkinson pressure bar. The mass percentage of the samples is 26.5% Al and 73.5% Teflon. The particle size of Teflon is 30 µm, and the particle size of Al is 1.5 µm and 100 µm, respectively. The microstructure of the sample was studied by scanning electron microscope (SEM). The results show that Al/Teflon reactive materials undergoes compression-yield-unloading-enhancement stages during the process of dynamic compression. The dynamic compressive strength of Al/Teflon reactive materials samples prepared by Al_1.5 µm/Teflon_30 µm and Al_100 µm/Teflon_30 µm are 55 MPa and 47 MPa at the strain rate of 4 × 10³ s⁻¹, respectively. When the Al particle diameter is 100 µm in Al/Teflon material, the strength contribution of Al is larger. However the defect is more obvious after yield, the strength is weaker than that of Al_1.5 µm/Teflon_30 µm sample.

使用Split Hopkinson压力棒分析了2种Al/Teflon反应材料样品的动态压缩行为。样品的质量百分比为 26.5% Al 和 73.5% Teflon。Teflon 的粒径为 30 µm，Al 的粒径分别为 1.5 µm 和 100 µm。通过扫描电子显微镜（SEM）研究样品的微观结构。结果表明，Al/Teflon反应材料在动态压缩过程中经历了压缩-屈服-卸载-增强阶段。由Al _{1.5 µm} /Teflon _{30 µm}和Al _{100 µm} /Teflon _{30 µm}制备的Al/Teflon反应材料样品在4×10 ³应变速率下的动态抗压强度分别为55 MPa和47 MPas ^-1，分别。当 Al/Teflon 材料中的 Al 粒径为 100 µm 时，Al 的强度贡献更大。但屈服后缺陷更明显，强度弱于Al _{1.5 µm} /Teflon _{30 µm}样品。
