Air blast wave protection |
摘要 |
Described embodiments include a system, device and method. A described device includes a layer of a first material configured to reflect a substantial portion of a specified incident air blast wave energy. The layer of the first material has an acoustic impedance substantially mismatched to air's acoustic impedance, and a thickness less than about 3 mm. The device includes a layer of a second material configured to attenuate a substantial portion of the specified incident air blast wave energy utilizing an inelastic response. At least a portion of a back surface of the first material is proximate to at least a portion of a front surface of the second material.
