Metal Matrix Composites FINDINGS Metal matrix composites (MMCs) usually con-sist of a low-density metal, such as aluminum or magnesium, reinforced with particulate or fibers of a ceramic material, such as silicon carbide or graphite. Compared with unreinforced metals, MMCs offer higher specific strength and stiffness,

Scientists also began looking at metal matrix composites (MMCs) for a solution. MMCs typically use an inorganic, ceramic fiber or particulate phase to add heat resistance to light-weight metals and to lower their coefficient of thermal expansion. The reinforcement can also add strength and stiffness, but toughness tends to be lower ...

A more likely situation is that the fiber and the matrix fail at different strains. One example of this could be a metal matrix composite represented by Fig. 5-4. In this case the fiber breaks in a brittle manner and the matrix exhibits ductility where the maximum strength occurs before final
