In order to study the dynamic compressive properties of reactive material which coating different shell thicknesses at various strain rates, Split Hopkinson Bar (SHPB) has bee used. The stress-strain curves at different strain rates were obtained under uniaxial stress loading condition. The results show that reactive materials and reactive fragments of coated structure have obvious strain rate effect. The yield strength of the 20# steel coating is 10 times higher than internal reactive material. The mechanical properties of coated reactive fragments are greatly affected by the thickness of the coating. The yield strength of the reactive fragments of the shell thickness of 1mm and 2mm cladding is 300MPa and 520MPa, respectively.
