Abstract: The present invention is a system for cooling high power, heat generating devices. The system includes a metal matrix composite (AlSiC) having a coefficient of thermal expansion substantially equal to that of the heat generating device. The metal matrix composite (MMC) includes interior cooling channels and at least one Pyrolytic Graphite insert laterally positioned against the cooling channels. The heat generating device is placed on the metal matrix composite top surface in a substantially parallel relationship with the Pyrolytic Graphite insert surface area for maximum heat transfer efficiency.

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.
