In order to find out the blast wave pressure attenuating property of cladding aluminum foam layer and aluminum foam sandwich layer, the analysis and numerical methods was used to study the blast wave pressure attenuating property of cladding aluminum foam layer and aluminum foam sandwich layer. The main impact factor of aluminum foam sandwich layer attenuating blast wave pressure also was disgusted by this paper. The results show that the aluminum foam layer and aluminum foam sandwich layer have the ability to attenuate the blast pressure before compressing to solid, and the ability decreasing after the aluminum foam was completely compressed. The blast attenuating property of aluminum foam and aluminum foam sandwich layer impacted by cell and relative density. The materials of face sheet also influenced the blast attenuating property of aluminum foam sandwich layer. The sandwich layer should be optimized to attenuate blast wave pressure, or its attenuating blast property may be not well for cladding aluminum foam and its sandwich layer.
