Abstract: The blast mitigation properties of an Explosafe aluminium mesh product have been evaluated using scaled arena tests. The blast mitigation abilities of the aluminium mesh were characterized and several specific conclusions were drawn from the data. First, the aluminium mesh reduced free-field pressure and impulse increasingly as the number of layers of mesh was increased. Also, pressure reduction and impulse reduction displayed contradicting behaviours, thus a design trade-off exists between pressure reduction and impulse reduction. As scaled distance increases, impulse reduction increases while pressure reduction decreases. For 20 layers of mesh at scaled distance 7.6, the pressure and impulse reductions converge at approximately 28%. This is quite an impressive reduction for such a lightweight and easy to handle material. This design tool was created utilizing the first two test methods. These tests began to investigate a lightweight blast mitigation option for the field.
