Protection module for protection against hollow charges includes layer sequence of three-dimensional metal grid structure or open-pore metal foam and air layers

摘要

The protection module contains material in the form of a three-dimensional metal grid structure or open-pore metal foam, 5-40 ppi thick. Solid or liquid material may fill the pores. The module can be structured as a series of layers (7, 9) in a housing with walls (2',3', 4', 5'), interleaved with layers of air (6, 8, 10).
