Abstract
A composite, layered shield for protecting a vehicle housing explosives in an ammunition stowage compartment from the detonation of said explosives while in said compartment. Said shield comprises, in a layered fashion, a first layer of an energy absorbing rubber, a pusher plate layer, a crush element layer, and a second layer of an energy absorbing rubber. In order to protect the vehicle, the ammunition stowage compartment is lined with the composite, layered shield of the present invention. The shield is mounted in such a manner that the energy absorbing rubber is closest to the explosives, followed by the pusher plate, then the crush element, and finally the second energy absorbing rubber layer. The overall areal density of the shield is about 17.6 pounds per square foot. Said shield is light weight and provides effective blast and shock protection for the walls of the explosive containing stowage compartment as well as for the vehicle housing the stowage compartment.
