TL;DR: Lightweight composite armor comprising a plurality of ceramic bodies embedded in a metal matrix is a common type of composite body as discussed by the authors, usually spherical alumina balls coated with a binder and ceramic particles.

TL;DR: A metal matrix composites are manufactured in a vacuum die casting machine as mentioned in this paper, where solid aggregate material is placed in a die (2, 5), the die is evacuated, and molten metal is driven by a piston (4) to infiltrate the solid aggregate materials where it subsequently solidifies to form a metal matrix composite.

TL;DR: In this article, a method of fabricating a metal matrix composite (MMC) containing electrically isolated areas is described. But the method is not suitable for the fabrication of complex structures.

TL;DR: In this article, a method of fabricating a metal matrix composite containing electrically isolated areas and the MMC formed from the method is presented, which includes: (a) providing a liquid pool of unreinforced aluminum alloy; (b) infiltrating the unreinforcing aluminum alloy into a stack comprising upper and lower porous preforms and an electrical insulator material placed between the preforms; (c) solidifying the liquid-phase metal to form a metal matrices composite product that completely surrounds the stack; and (d) forming at least one groove in the solid
