Abstract : This patent discloses a structure for attenuating explosive shock waves to prevent propagation of accidental explosions by sympathetic detonation of adjacent explosive. It comprises bidirectionally symmetric layers of material of consecutively increasing or decreasing acoustic impedance laminated about a center layer. The structure may be made by combining several materials, as in consecutive layers of aluminum, plastic, and a rigid foam surrounding on both sides a layer of steel; or, two materials, as in a center layer of Kevlar TM surrounded on both faces with layers of plastic. The plies comprising the layer of Kevlar TM are canted with respect to the plastic layers. Patents. (EDC)
