Abstract
A lightweight armor system may comprise multiple reinforcement materials layered within a single metal matrix casting. These reinforcement materials may comprise ceramics, metals, or other composites with microstructures that may be porous, dense, fibrous or particulate. Various geometries of flat plates, and combinations of reinforcement materials may be utilized. These reinforcement materials are infiltrated with liquid metal, the liquid metal solidifies within the material layers of open porosity forming a dense hermetic metal matrix composite armor in the desired product shape geometry. The metal infiltration process allows for metal to penetrate throughout the overall structure extending from one layer to the next, thereby binding the layers together and integrating the structure.
